Simplify matrix configuration for CI workflows (#1213)
Addresses https://github.com/llvm/torch-mlir/issues/1207. 

#### Provisioned jobs:
```
# ubuntu - x86_64 - llvm in-tree     - pytorch binary - build+test    # most used dev flow and fastest signal
# ubuntu - x86_64 - llvm out-of-tree - pytorch source - build+test    # most elaborate build
# macos  - arm64  - llvm in-tree     - pytorch source - build only    # cross compile, can't test arm64
```

#### Main changes
- [x] Spawn macos builds from a separate matrix (in the same workflow). It made sense to do this as they are fairly different from ubuntu (cross compile, use a different cmake configuration). This simplifies the matrix configuration and exclusions quite a bit, and makes the workflow a bit more tractable and maintenance friendly.
- [x] Remove the submodule md5sum step for ccache config. This was [broken](https://github.com/llvm/torch-mlir/runs/7779288734?check_suite_focus=true#step:3:145) for a while now.
- [x] Removes unused matrix options - `os`, `targetarch`, `python-version`, `llvmtype`.
- [x] Address ZSTD [comment](https://github.com/llvm/torch-mlir/pull/1204#discussion_r942349282) on @powderluv's cross compile [PR](https://github.com/llvm/torch-mlir/pull/1204). 

#### Further improvements (to be addressed in follow-on):
* ubuntu-x86_64 out-of-tree integration tests fail ([error](https://github.com/sjain-stanford/torch-mlir/runs/7781264029?check_suite_focus=true)); only run unit tests for now (tests are excluded in current CI too)

#### Passing workflow:

Jae Hoon (Antonio) Kim d9aee0d7a7 E2E HuggingFace Bert using LTC Backend (#912)
* Update native function definitions

* Add ops to support bert lowering

- Add empty_strided and as_strided

- Restore zeros_like to op blacklist (Without this, tensors will be unintentionally created with a CPU device rather than lazy)

- Check for composite implicit ops and add device data IR

- Also fix codegen for functionalization

* Add autogen to CMakeList

* Remove PyTorch submodule

* Reduced BERT model size

* Print Mark Step status in Torch MLIR LTC debug string

* Apply fixes to work with latest upstream/main

- Pass importOptions into getMlirTypeFromTorchType during NodeImporter::importNode

  Without this, the tensor type created may have a mismatched type as ImportOptions may cause vtensor to be used instead of tensor

* Update shape inference functions

- Fixed compute_shape_native_batch_norm when mean and var are uninitialized

  Previously, the number of shapes returned would be <3 if either mean or val was didn't exist. Instead, we now initialize them with a vector matching the number of channels.

- Implemented compute_shape_mul

- Fixed bug in reshape shape inference error message

* Get MLIR backend more consistent with TS backend

- Remove LazyNativeFunctions::_unsafe_view from autogen

- Blacklist ops to make JIT graph more like output of TS backend

- Print graph when SSA value has mismatch of types and results

- Remove normalize_index from LazyShapeInference

- Fix seeds for LTC example models

* Update and clean up shape inference functions

- Prune shape inference functions

- Add shape inference function for GenerateSlice

- Add shape inference function for GenerateCopy

Henry Tu cca9fe126e Enable support for LTC Input/Output Mapping (#764)
* Save InputOutputAliases to TorchMlirComputation

* Implement GetResultShape for TorchMlirLoweringContext

* Use optional return type for GetResultShape

* Remove support for aten::detach

With this op enabled, tensors were being copied, which resulted in incorrect aliasing.

* Add newline before printing I/O alias mapping

* Changed printout to use "Input param" as label instead of "Input"

* Remote shape inference function for aten::detach

* Moved implementation of SetUpAlias to MlirLoweringContext

As part of this change, TorchMlirComputation has been moved to the end of mlir_lowering_context.h so that it can access some new structs in TorchMlirLoweringContext

* Use updated PyTorch API

* Remove GetResultShape

Complements this upstream PyTorch PR: pytorch/pytorch#75828

This PR adds support for mapping input and output tensors which alias each other. (e.g. maps input weight tensor in parameter to the same tensor in output after a training iteration)

MLIR: 
func @graph(%arg0: !torch.vtensor<[1,5],f32>, %arg1: !torch.vtensor<[1],si64>, ..., %arg6: !torch.vtensor<[10,5],f32>, %arg7: !torch.vtensor<[10],f32>, ...) {
  ...
  return %arg0, %arg1, %17, %23, ... : !torch.vtensor<[1,5],f32>, !torch.vtensor<[1],si64>, !torch.vtensor<[10,5],f32>, !torch.vtensor<[10],f32>, ...
}

Input/Output Alias Mapping: 
Output: 0 -> Input: 0
Output: 1 -> Input: 1
Output: 2 -> Input: 6
Output: 3 -> Input: 7
The aten::detach op has also been disabled in this PR to fix the issue of tensors not aliasing properly due to copying.

Henry Tu 3e9b1cbd36 Added JIT to MLIR lowering (#724)
* Added JIT to MLIR lowering

Lowering to JIT is performed in a way similar to how it's done in the TS LTC backend. After a jit::Graph is constructed, it gets converted to a jit::Function, which is fed into the existing utility to generate an MlirModule in torch-mlir.

* Renamed `csrc/backend` to `csrc/base_lazy_backend`

build: improve robustness of cmake and shell scripts (#1018)
On my local machine, `unzip` didn't exist (producing a "command not
found" error), but CMake ignored the error.  Although the build did
succeed (because it found a previously-built version of libtorch), it
seems better to abort builds on such failures, so this patch checks the
return code of all external process invocations.

Along similar lines, this patch also updates the shell scripts in
`build_tools` to extensively use double-quoting to prevent unintentional
word splitting or globbing.  Since some of the scripts execute `rm`
while using shell variables, this patch also adds the preamble `set -u`
to abort execution if an undefined variable is referenced, so that we
reduce the chances of executing `rm -rf /` if the path expression
happens to refer to an undefined variable.

Allow torch-mlir to support PyTorch extensions. (#895)
PyTorch allows new operators to be registered dynamically in modules.
Torch-mlir already makes it fairly straightforward to add support for
new operators, and this commit just extends that support to allow new
PyTorch ops to come from a external module.

This does *not* allow ops to be dynamically loaded into torch-mlir.
Torch-mlir must still be compiled with support built-in.

Add a `_torch_mlir_custom_op_example` subpackage to `torch_mlir` which
registers an demonstration op. It will not be imported by default when
importing torch_mlir. It's strictly for testing and documentation.

Adds an end-to-end test for the `torch_mlir_custom_op_example::identity` op.

With all these changes, we should now be actively testing PyTorch extension
support with all future patches.

* Add oneshot release snapshot for test/ondemand

Add some build scripts to test new release flow based on IREE.
Wont affect current builds, once this works well we can plumb it
in.

Build with manylinux docker

* Fixes a few issues found when debugging powderluv's setup.

* It is optional to link against Python3_LIBRARIES. Check that and don't do it if they don't exist for this config.
* Clean and auditwheel need to operate on sanitized package names. So "torch_mlir" vs "torch-mlir".
* Adds a pyproject.toml file that pins the build dependencies needed to detect both Torch and Python (the MLIR Python build was failing to detect because Numpy wasn't in the pip venv).
* Commented out auditwheel: These wheels are not PyPi compliant since they weak link to libtorch at runtime. However, they should be fine to deploy to users.
* Adds the --extra-index-url to the pip wheel command, allowing PyTorch to be found.
* Hack setup.py to remove the _mlir_libs dir before building. This keeps back-to-back versions from accumulating in the wheels for subsequent versions. IREE has a more principled way of doing this, but what I have here should work.

Sean Silva b69db60f85 Pin the Python package to the exact PyTorch nightly.
This avoids issues where PyTorch version drift has made things
incompatible.

One caveat is that you will need to specify
`-f https://download.pytorch.org/whl/nightly/cpu/torch_nightly.html
--pre` on the command line for pip to know where to find the nightly
packages (there is no way around this) -- this is easiest to do by
simultaneously passing `-r requirements.txt` on the pip command line.

Sean Silva 729402c3f4 Reduce compilation time for TorchOps.cpp.inc
The `assemblyFormat` stuff (which generates unrolled, per-op C++ code)
was taking up a lot of compile time, and all the ops are essentially
printed with the same logic. So this PR makes them all call the same
helper function. This is done by using
`let hasCustomAssemblyFormat = 1` and then implementing `FooOp::parse`
and `FooOp::print`.

Additionally, the `Generated*Ops.td` files are all collapsed into just
`GeneratedTorchOps.td` (there is no reason to have the files separate,
since the files are very large anyway so one is always having to search
within them -- editors don't care that the file to search is now a bit
bigger :) ).

This reduces TorchOpsODSGenerated.cpp compile time (which is now
GeneratedTorchOps.cpp) from 39 to 31 seconds on my machine. This is
actually less than I expected, but this PR is an overall cleanup to the
code anyway. The next step will be to introduce (better) functionality
upstream for sharding the TorchOps.cpp.inc file, so that we can truly
parallelize the O(#ops) costs. This is also necessary, because after
this PR, TorchDialect.cpp is now the slowest file to compile, due to the
`addOperations<... all the ops ...>` call, which needs to be shareded
too.

Sean Silva 3734f69119 Remove basic_mt from the heavydep tests
This was an aspirational goal at an earlier stage in the project where
the focus was heavily on programs with state, control flow, and
lists/dicts. We will circle back to such programs likely 2022H2 at some
point, but for now, having this test doesn't add much, since basically
nothing works or is being worked on.
2022-03-15 15:25:53 -07:00
Sean Silva a5fe0cf063 Introduce new shape library design.
See the documentation in `docs/shape_lib.md` and
`docs/adding_a_shape_function.md` for an overview of the system.

This completely overhauls how we represent shape functions. In
particular, RefineTypes does not infer shapes anymore (only dtypes).
Shape functions are now written in (TorchScript'able) Python.

Recommended review order:

1. Read `docs/shape_lib.md` and `docs/adding_a_shape_function.md`.
1. Code and tests for ReifyShapeCalculations, DropShapeCalculations.
1. Code and tests for SimplifyShapeCalculations.
1. shape_lib_gen.py
1. Code and tests for new RefineTypes pass.
1. Random folders/canonicalizers in TorchOps.cpp and associated test in
   `canonicalize.mlir`.
1. New ReadOnly trait inferred from the registry.
1. Any miscellaneous remaining stuff.

Sean Silva 404bd74ddf Port the bulk of the remaining code to torch-mlir
This leaves no real code outside torch-mlir.

This also renames the "npcomp backend contract" to "linalg on tensors
backend contract" as the name of the abstraction layer that RefBackend
(IREE too) accepts.

Sean Silva 3dc9b4ee2f Remove some more old stray files. 2021-09-22 16:13:03 -07:00
Sean Silva 1a0b953ea7 Eliminate almost all mentions of IREE.
A few remain in examples/docs that will be naturally be updated in due
time.

This regresses the list support and the general direction of more widely
supported control flow, lists/dicts/globals that we were going for with
the TorchScript path. The idea is that we are deferring that work to
make torch-mlir a very clean standalone thing. We will reboot it,
probably using some of the tools of iree_pydm to make it simpler, and in
a more natural place (such as an iree-torch repo that depends on IREE and
torch-mlir to build a working PyTorch frontend solution for IREE -- it
was really weird that npcomp depended on IREE).

Sean Silva 5f3b1ce0b8 Fold torch_mlir_dialects python package into `torch_mlir`.
After this change, there are now just two subdirectories in the
`python_packages` directory in our combined build:
- `npcomp_core` with all the npcomp stuff
- `torch_mlir` with all the `torch-mlir` stuff.

The combined `torch_mlir` build will be packaged for use by `pip`.
There isn't anything super useful for wider use in `npcomp_core` so for
now we aren't going to package that one.

Sean Silva 0eb767ea45 Remove frontends/pytorch directory.
It just contained the e2e testing framework. We now fold it into the
main project to reduce complexity.

- `frontends/pytorch/python/` -> `python/torch_support`
- `frontends/pytorch/e2e_testing -> e2e_testing`
- `frontends/pytorch/examples -> examples`
- `frontends/pytorch/test` -> `python/test`
- `torch_mlir_torchscript` python module -> `npcomp_torchscript`
- `torch_mlir_torchscript_e2e_test_configs` python module ->
  `npcomp_torchscript_e2e_test_configs`

This also changes the license of a handful of files from the
"pytorch-style" license to the regular LLVM/npcomp license. The only
people who committed to those files were myself and Yi.

Sean Silva b6be96d722 [torch-mlir earthmoving (2/N)] Python code movement.
This moves the bulk of the Python code (including the Torch interop)
from `frontends/pytorch` into `torch-mlir/TorchPlugin`. This also
required reconciling a bunch of other Python-related stuff, like the
`torch` dialects.

As I did this, it was simpler to just remove all the old numpy/basicpy
stuff because we were going to delete it anyway and it was faster than
debugging an intermediate state that would only last O(days) anyway.

torch-mlir has two top-level python packages (built into the
`python_packages` directory):

- `torch_mlir_dialects`: `torch` dialect Python bindings (does not
  depend on PyTorch). This also involves building the aggregate CAPI for
  `torch-mlir`.
- `torch_mlir`: bindings to the part of the code that links against
  PyTorch (or C++ code that transitively does).

Additionally, there remain two more Python packages in npcomp (but
outside `torch-mlir`):

- `npcomp_torch`: Contains the e2e test framework and testing configs
  that plug into RefBackend and IREE.
- `npcomp_core`: Contains the low-level interfaces to RefBackend and
  IREE that `npcomp_torch` uses, along with its own
  `MLIR_PYTHON_PACKAGE_PREFIX=npcomp.` aggregation of the core MLIR
  python bindings. (all other functionality has been stripped out)

After all the basicpy/numpy deletions, the `npcomp` C++ code is now very
tiny. It basically just contains RefBackend and the `TorchConversion`
dialect/passes (e.g. `TorchToLinalg.cpp`).

Correspondingly, there are now 4 main testing targets paralleling the
Python layering (which is reflective of the deeper underlying dependency
structure)

- `check-torch-mlir`: checks the `torch-mlir` pure MLIR C++ code.
- `check-torch-mlir-plugin`: checks the code in `TorchPlugin` (e.g.
  TorchScript import)
- `check-frontends-pytorch`: Checks the little code we have in
  `frontends/pytorch` -- mainly things related to the e2e framework
  itself.
- `check-npcomp`: Checks the pure MLIR C++ code inside npcomp.

There is a target `check-npcomp-all` that runs all of them.
The `torch-mlir/build_standalone.sh` script does a standalone build of
`torch-mlir`.

The e2e tests (`tools/torchscript_e2e_test.sh`) are working too.

The update_torch_ods script now lives in
`torch-mlir/build_tools/update_torch_ods.sh` and expects a standalone
build.

This change also required a fix upstream related to cross-shlib Python
dependencies, so we also update llvm-project to
8dca953dd39c0cd8c80decbeb38753f58a4de580 to get
https://reviews.llvm.org/D109776 (no other fixes were needed for the
integrate, thankfully).

This completes most of the large source code changes. Next will be
bringing the CI/packaging/examples back to life.
2021-09-15 13:40:30 -07:00
Sean Silva 28a7738189 [torch-mlir earthmoving (1/N)] C/C++ code movement.
This creates the `external/torch-mlir` directory as an
LLVM_EXTERNAL_PROJECTS-compatible project (analogous to
`iree-dialects`) and completes movement/rename of all pure MLIR C/C++
compiler code into there. The next step will be to move all the Python
code / code that links/includes PyTorch C++ code (which currently lives
in `frontends/pytorch`) into a subdirectory here.

I call this "earthmoving" because it is mostly mechanical changes and
renames. As a quick summary (we can change this down the road easily)
- C++ `mlir::NPCOMP::Torch -> mlir::torch::Torch`
- CAPI `npcompTorchListTypeGet -> torchMlirTorchListTypeGet`
- preprocessor `#ifndef NPCOMP_ -> #ifndef TORCHMLIR_`
- CMake `NPCOMPFoo -> TorchMLIRFoo`

The goal of this is to create a standalone project creating a center of
mass for entry into the MLIR ecosystem from PyTorch, suitable in scope
for eventual inclusion/ownership in PyTorch. The idea is that
`external/torch-mlir` will some day be pulled out into its own
repository, and then npcomp will simply pull it in as a submodule.

Layering-wise, what lives in `torch-mlir` lowers code from PyTorch
(currently TorchScript, but TorchFX or pytorch/xla-style tracing are
possible extensions) down to what we have been calling the "Torch
backend contract" which is cleaned up IR (inlining, simplifcation,
conversion to value tensors, ...) entirely in the `torch` dialect. This
is the branching off point for further lowering, of which npcomp takes
one opinion (outside `torch-mlir` of course!), namely the
`TorchConversion` dialect/transforms which lower to IR suitable for IREE
and other linalg-on-tensors based lower-level compilers.

Summary of changes:
- move `{include,lib,test}/Dialect/Torch` into `torch-mlir`
- move relevant parts of CAPI into `torch-mlir`.
- leave a few things related to the `torch-mlir` Python build commented
  out, which should be resolved in a subsequent change.
2021-09-10 21:44:37 -07:00
Sean Silva 0b7dbf5f81 Initial import of iree-dialects.
We plan on using these dialects "natively" as part of the npcomp backend
contract, and provide feedback to evolve them in IREE. Roughly speaking,
we can consider these dialects as "what's missing from upstream that we
think belongs in the general abstraction layer that npcomp's backend
contract targets".

We integrate them by just copying the relevant directory from the IREE
source tree (with `build_tools/update_iree_dialects.sh`). This avoids
adding IREE as a submodule, which is way too heavyweight (including
IREE itself, another copy of LLVM, TensorFlow, ...) and would give the
false impression of a source dependency rather than the lightweight (and
eventually versioned/stabilized) IR-level compatibility that we strive
for.

Yi Zhang bfc3ee35c6 Import Machine Translation model to MLIR.
This includes the following changes to import MT model into MLIR. There
are still a lot of work to for actual compilation.
- Add `torch.dict<>`, `torch.any`, `torch.number` types
- Add `torch.prim.DictConstruct` op
- Fix `torch.prim.TupleConstruct` op assembly format to include resulting types
2021-08-10 15:22:06 -04:00
Sean Silva 453e29ea05 Add E2E support for tests with heavy dependencies (heavydep tests).
The tests use the same (pure-Python) test framework as the
normal torchscript_e2e_test.sh, but the tests are added in
`build_tools/torchscript_e2e_heavydep_tests` instead of
`frontends/pytorch/e2e_testing/torchscript`. Any needed dependencies can
easily be configured in generate_serialized_tests.sh.

We add an initial machine translation model with a complex set of
dependencies to seed the curriculum there. I verified that this model
gets to the point of MLIR import (it fails there with a segfault due to
not being able to import the "Any" type).

This required moving a few files from the `torch_mlir` Python module
into multiple modules to isolate the code that depends on our C++
extensions (which now live in `torch_mlir` and
`torch_mlir_torchscript_e2e_test_configs`) from the pure Python code
(which now lives in `torch_mlir_torchscript`). This is an entirely
mechanical change, and lots of imports needed to be updated.

The dependency graph is:
```
       torch_mlir_torchscript_e2e_test_configs
                  /              |
                 /               |
                /                |
               V                 V
torch_mlir_torchscript       torch_mlir
```

The `torch_mlir_torchscript_e2e_test_configs` are then dependency-injected
into the `torch_mlir_torchscript` modules to successfully assemble a
working test harness (the code was already structured this way, but this
new file organization allows the isolation from C++ code to actually
happen).  This isolation is critical to allowing the serialized programs
to be transported across PyTorch versions and for the test harness to be
used seamlessly to generate the heavydep tests.

Also:
- Extend `_Tracer` class to support nested property (submodule) accesses.

Recommended review order:
- "user-level" docs in README.md
- code in `build_tools/torchscript_e2e_heavydep_tests`.
- changes in `torch_mlir_torchscript/e2e_test/framework.py`
- misc mechanical changes.

Sean Silva 2efda323ff Significantly restructure torch/aten import design.
This is a really major and invasive restructuring of the way we get
torch operators (`torch::jit::Operator` / `c10::OperatorHandle`) into
MLIR. Please forgive the challenging review, but due to the sheer
invasiveness, it wasn't really practical do do it in sane smaller
pieces.

This fully replaces everything that was already working on the
TorchScript path (actually, more -- we added tanh support to
TorchToLinalg in order to delete the older code paths). Additionally,
I've kept the lights on for the acap path too, including what little e2e
stuff was working before (for expediency I made a few tiny compromises
along the way that will be easy to undo when we give that path proper
attention).

Overview of the new design:
- The torch operator `somens::someunqualname.someoverloadname` is
  imported as `torch.somens.someunqualname.someoverloadname` (skip the
  last dotted part if the overload name is empty), OR, if we don't have
  such an op registered, it is imported as
  `torch.operator "somens.someunqualname.someoverloadname" (...) : ...`.
  - The addition of the "overload name" is a critical element here, as
    the `(ns,unqual,overload)` triple is unique, which solves a lot of
    problems we were having.
  - This involves having separate MLIR ops for the `trailing_` and
    `.out` variants and all the different overloads. This seemed
    necessary, because the set of overloads is so wild and varied and
    unstructured. The previous design was leaning into some underlying
    structure that just isn't there -- the default situation is
    the "random overload that we want to manage on the MLIR side",
    rather than that being an exception. E.g.  `aten::ne` (not-equal)
    has 21 overloads, only 4 of which are c10 dispatcher ops see
    [gist](https://gist.github.com/silvasean/190ba918c550c956260e21254e1b8aa1),
    and the "out" variant is really called `.Tensor_out` instead of
    `.out` as it frequently is for other ops.
  - Rationale for all being in `torch` namespace: the set of operators
    are so varied and unstructured that "dialect per namespace"
    doesn't result in anything resembling the typical MLIR dialect
    boundary expectations. We could maybe draw the boundary at
    dispatcher ops vs non-dispatcher ops, but that doesn't seem to
    really result in very much useful structure at this point in time.
  - Note: within the torch operator registry, we effectively have a
    mini-basicpy subdialect (already type-resolved), which is reasonably
    structured.
  - The existing Torch op interfaces are also removed -- now that we
    track the overload name, we can losslessly find the original
    operator.
- Instead of `ATenRecognizeKernelsPass`, we now have a
  `ReduceOpVariantsPass` that keys off certain traits (and perhaps
  eventually interfaces) to reduce variants of ops to a smaller set,
  ideally operating on immutable tensors and using surrounding ops to
  model the mutability/aliasing aspects.
  - Note: `torch.ns.unqual.overload` ops allow both immutable and
    mutable tensors (unlike the previous hard distinction in the common
    case). This is a premonition for a future change that will introduce a
    bona fide `!torch.tensor` type that will clean up a bunch of stuff.
- `TorchToLinalg` / `TorchToStd` supercede the existing
  "ATen->TCF->TCP->Linalg" path.
- The new `torch_ods_gen.py` supercedes `torch_signature_ods_gen.py`.
  It should look somewhat familiar, but the benefit of hindsight has
  allowed a lot of simplifications.

The overall trend seems to be to make the `torch` dialect a nice layer
independent of anything else. It feels like as a natural result of
various future changes we will be removing the reliance on basicpy+numpy
dialects and have a nice self-contained type system too that properly
models the TorchScript type system (including proper subtyping,
mutable/immutable tensors, optional dtype, etc.).

Recommended review order:
- Start at some of the new import IR, e.g. in
  `frontends/pytorch/test/node_import/prim.py`,
  `frontends/pytorch/test/acap_export/test_export_add3.py`, and other
  tests.
- `frontends/pytorch/python/torch_mlir_utils/codegen/torch_ods_gen.py`
  and associated generated files:
  - `include/npcomp/Dialect/Torch/IR/GeneratedAtenOps.td`
  - `include/npcomp/Dialect/Torch/IR/GeneratedPrimOps.td`
- Inspect `ReduceOpVariants.cpp` / `reduce-op-variants.mlir` and the new
  traits in `include/npcomp/Dialect/Torch/IR/TorchTraits.h`
- Various code changes in the import path in
  `frontends/pytorch/csrc/builder`. Probably most interesting is the new
  code in `torch_to_mlir_utils.cpp` that has the logic to create the
  `torch.operator` ops or `torch.ns.unqual.overload` ops.

This is the [new ResNet IR](https://gist.github.com/silvasean/5407aafb710d07612b7b5b92eabecebe),
just to be able to look at a substantial sample of IR in the new style.

Stella Laurenzo af4edb63ae Start reworking towards a shared library build.
* Need to have a dag of shared library deps in order to interop across python extensions (as presented in ODM).
* Introduced add_npcomp_library and friends to mirror the MLIR setup.
* Adds a libNPCOMP.so shared library.
* Redirects tools and extensions to link against libNPCOMP.so (instead of static libs).
* Moves all libraries to lib/, all binaries to bin/ and all python extensions to python/. The invariant is that the rpaths are setup to have a one level directory structure.
* Reworks the _torch_mlir extension to build like the others (still need to come up with a consolidated rule to do this instead of open coded).
* Includes an upstream version bump to pick up needed changes.

Sizes with dynamic linking (stripped, release, asserts enabled):
  libNPCOMP.so: 43M (includes much of the underlying LLVM codegen deps)
  libMLIR.so: 31M
  _npcomp.so: 1.6M (python extension)

* Installs new-clang and LLD and configures environment to use it (otherwise, link time is terrible).
* Fixes a gcc compile error (in the off chance you build with default gcc compiler).
* Tests are failing based on some dialect registration stuff that must not have been factored correctly. Will followup with a fix.

Stella Laurenzo 4c37aed841 Update build instructions to use the submodule for llvm.
* Previous instructions were referring to the option to use an external llvm-project checkout with a stale version hash.

Add mlir-hlo as a submodule and add a script to find versions. (#20)
* I expect that mlir-hlo will be a non-optional dependency of the project, so adding as a sub-module.
* IREE is an optional dependency and I'm keeping this as an out-of-tree checkout for the moment.
* The script will compute the join across both iree and mlir-hlo to find a common LLVM version.
* The script needs some more work (like a flag that says to update the version, etc). Likely needs more testing through an integrate or two.

Sean Silva b4f0cea8fa Rework e2e flow to use new "npcomprt"
This ~totally reworks the existing "runtime" stuff to be more
principled and usable, such as from Python. It's still not fully
production-quality, mainly in the department of memory management (e.g.
it currently leaks memory; we need to figure out "who frees memrefs" +
the analysis and transformation needed to do that (maybe use upstream
buffer allocation pass?)).

The user API is in include/npcomp/runtime/UserAPI.h, though
include/npcomp/JITRuntime/JITModule.h is a friendlier wrapper.

The stuff under {include,lib}/runtime is totally firewalled from the
compiler and tiny (<6kB, though no attention has gone into optimizing
that size). For example, we don't link in libSupport into the runtime,
instead having our own bare bones replacements for basics like ArrayRef
(the JITRuntime helps with bridging that gap, since it *can* depend on
all common LLVM utilities).

The overall features of npcomprt is that it exposes a module that
with multiple function entry points. Each function has arguments and
results that are tensor-valued, and npcomprt::Tensor is the runtime type
that is used to interact with that (and a npcomprt::Ref<T>
reference-counting wrapper is provided to wrap npcomprt::Tensor in the
common case).

From an implementation perspective, an npcomprt module at the
LLVM/object/binary level exposes a single module descriptor struct that
has pointers to other metadata (currently just a list of function
metadata descriptors). All interactions with the npcomp runtime are
keyed off of that module descriptor, including function lookups and
dispatching. This is done to dodge platform ABI issues and also allow
enough reflection to e.g. verify provided arguments.

Most of the compiler-side work here was in LowerToNpcomprtABI and
LowerToLLVM.

Also,
- Rename npcomp_rt/NpcompRt to npcomprt/Npcomprt; it was getting
annoying to type the underscores/caps.
- misc improvements to bash_helpers.sh

Stella Laurenzo e1839a0d6b Bump llvm and iree versions.
* Gets us passed the upstream changes that enable type interfaces.
* Adds the ARM backend due to an implicit IREE dependency sneaking in for that (https://github.com/google/iree/issues/2401)
* Adds explicit TypeStorage to type base classes per upstream change.
