Move TorchConversion dialect and TorchTo* into torch-mlir

Generalize support for elementwise ops. We plumb through e2e a fair number of interesting cases: - unary, binary, ternary elementwise ops - ops like `torch.aten.add.Tensor` that also take a scalar parameter - static size-1 broadcasting We allow the static size-1 broadcasting case, but emit a runtime error in the case of dynamic size-1 broadcasting. This seems like a sweet spot subset of things that can be lowered directly to linalg, while not being overly constraining to users. This is consistent with what IREE is doing for CHLO->Linalg lowering as well ([code](https://github.com/google/iree/blob/50bf7a87e465d2048c527bc27724edde40519b7e/iree/compiler/InputConversion/MHLO/BroadcastingToLinalgPatterns.cpp#L1)). To test the static size-1 case, we added support for the `torch.aten.unsqueeze` op and lowering for it through `linalg.tensor_expand_shape`. This involved a generalization of `MaximizeValueSemantics` able to handle it (the solution there also works for `torch.aten.flatten.using_ints` which we need for ResNet anyway) Also, a few minor additional changes: - Add `VerifyInvariantsBeforeBackendLowering` pass, which catches a large class of errors before we get to backend lowering (now that we are doing dialect conversion, the errors are way nicer if we just emit them up front rather than in the guts of a random pattern). - Minor change to RefBackend to allow `linalg.tensor_expand_shape`. Recommended review order: - e2e tests in elementwise.py - `ConvertElementwiseOp` in TorchToLinalg.cpp + elementwise.mlir test - `ConvertAtenUnsqueezeOp` in TorchToLinalg.cpp + unsqueeze.mlir test - RefineTypes.cpp + tests - MaximizeValueSemantics changes + test - VerifyInvariantsBeforeBackendLowering pass + test

Add TorchToIREE and factor out TorchConversion dialect. This converts a basic list op (torch.prim.ListConstruct) to the IREE dialect. ``` def forward(self, x: float): return [x, x] ``` turns into: ``` builtin.func @forward(%arg0: !torch.float) -> !torch.list<!torch.float> { %0 = torch.prim.ListConstruct %arg0, %arg0 : (!torch.float, !torch.float) -> !torch.list<!torch.float> return %0 : !torch.list<!torch.float> } ``` which turns into: ``` builtin.func @forward(%arg0: f64) -> !iree.list<f64> { %c1 = constant 1 : index %c0 = constant 0 : index %c2 = constant 2 : index %0 = iree.list.create %c2 : !iree.list<f64> iree.list.set %0[%c0], %arg0 : !iree.list<f64>, f64 iree.list.set %0[%c1], %arg0 : !iree.list<f64>, f64 return %0 : !iree.list<f64> } ``` As part of doing this, I realized that it was time to formalize the IR form that we reach right before running TorchTo{Linalg,Std,...}. We now call it the "Torch backend contract". We then lower the "Torch backend contract" to the "npcomp backend contract", which involves the new TorchConversion (`torch_c`) dialect, which holds ops that need to operate on both the npcomp backend types (e.g. builtin tensors, i1, IREE list, etc.) and the `!torch` types. This made more sense, as I realized that if I didn't factor out `torch_c` then the Torch dialect would have a dependency on IREE dialect (we previously didn't notice this was an issue because we only depended on `builtin` types), which seemed wrong to me. Recommended review order: - TorchToIREE.cpp / `TorchToIREE/basic.mlir` - Look at the new structure of createTorchScriptToNpcompBackendPipeline. It now lives in TorchConversion/Transforms/Passes.cpp and cleanly calls into `Torch::createTorchScriptToTorchBackendPipeline` for the frontend lowering to the Torch backend contract. - Mechanical change extracting `torch_c.{to,from}_{i1,i64,f64,builtin_tensor,iree_list}` into a new TorchConversion dialect, and a few passes specific to the lowering from the Torch backend contract to the npcomp backend contract. - Minor fixes to TorchToLinalg.cpp to use unconverted operands (now that we convert lists as part of operand materialization, we need to use the original operands). Also added test for AtenMaxPool2dOp and fixed m_TorchConstantIntList. - TmpDeleteDeadIREELists pass. Temporary pass for deleting dead IREE lists that are created as part of operand materialization for conv/max pool/avg pool ops in TorchToLinalg.

build: update llvm tag to 4546397e (#1502) This commit makes the following changes needed to update bump LLVM: - Replace `linalg.init_tensor` with `tensor.empty` (see: https://reviews.llvm.org/D135129) - Replace `NoSideEffect` with `Pure` (see https://reviews.llvm.org/D135505) - Replace `body` region accessor for `ReduceOp` and `ReduceWindowOp` with `getBody` - Fix incorrect use of `tosa::ReduceSumOp` in `AtenNativeLayerNormOp` conversion pattern. The result type of `tosa::ReduceSumOp` must have the same rank as the input type.

build: update llvm tag to 4546397e (#1502) This commit makes the following changes needed to update bump LLVM: - Replace `linalg.init_tensor` with `tensor.empty` (see: https://reviews.llvm.org/D135129) - Replace `NoSideEffect` with `Pure` (see https://reviews.llvm.org/D135505) - Replace `body` region accessor for `ReduceOp` and `ReduceWindowOp` with `getBody` - Fix incorrect use of `tosa::ReduceSumOp` in `AtenNativeLayerNormOp` conversion pattern. The result type of `tosa::ReduceSumOp` must have the same rank as the input type. (see: https://www.mlplatform.org/tosa/tosa_spec.html#_reduce_sum) Co-authored-by: Ashay Rane <ashay@users.noreply.github.com> Co-authored-by: Ashay Rane <ashay@users.noreply.github.com>

Generalize support for elementwise ops. We plumb through e2e a fair number of interesting cases: - unary, binary, ternary elementwise ops - ops like `torch.aten.add.Tensor` that also take a scalar parameter - static size-1 broadcasting We allow the static size-1 broadcasting case, but emit a runtime error in the case of dynamic size-1 broadcasting. This seems like a sweet spot subset of things that can be lowered directly to linalg, while not being overly constraining to users. This is consistent with what IREE is doing for CHLO->Linalg lowering as well ([code](https://github.com/google/iree/blob/50bf7a87e465d2048c527bc27724edde40519b7e/iree/compiler/InputConversion/MHLO/BroadcastingToLinalgPatterns.cpp#L1)). To test the static size-1 case, we added support for the `torch.aten.unsqueeze` op and lowering for it through `linalg.tensor_expand_shape`. This involved a generalization of `MaximizeValueSemantics` able to handle it (the solution there also works for `torch.aten.flatten.using_ints` which we need for ResNet anyway) Also, a few minor additional changes: - Add `VerifyInvariantsBeforeBackendLowering` pass, which catches a large class of errors before we get to backend lowering (now that we are doing dialect conversion, the errors are way nicer if we just emit them up front rather than in the guts of a random pattern). - Minor change to RefBackend to allow `linalg.tensor_expand_shape`. Recommended review order: - e2e tests in elementwise.py - `ConvertElementwiseOp` in TorchToLinalg.cpp + elementwise.mlir test - `ConvertAtenUnsqueezeOp` in TorchToLinalg.cpp + unsqueeze.mlir test - RefineTypes.cpp + tests - MaximizeValueSemantics changes + test - VerifyInvariantsBeforeBackendLowering pass + test

Add TorchToIREE and factor out TorchConversion dialect. This converts a basic list op (torch.prim.ListConstruct) to the IREE dialect. ``` def forward(self, x: float): return [x, x] ``` turns into: ``` builtin.func @forward(%arg0: !torch.float) -> !torch.list<!torch.float> { %0 = torch.prim.ListConstruct %arg0, %arg0 : (!torch.float, !torch.float) -> !torch.list<!torch.float> return %0 : !torch.list<!torch.float> } ``` which turns into: ``` builtin.func @forward(%arg0: f64) -> !iree.list<f64> { %c1 = constant 1 : index %c0 = constant 0 : index %c2 = constant 2 : index %0 = iree.list.create %c2 : !iree.list<f64> iree.list.set %0[%c0], %arg0 : !iree.list<f64>, f64 iree.list.set %0[%c1], %arg0 : !iree.list<f64>, f64 return %0 : !iree.list<f64> } ``` As part of doing this, I realized that it was time to formalize the IR form that we reach right before running TorchTo{Linalg,Std,...}. We now call it the "Torch backend contract". We then lower the "Torch backend contract" to the "npcomp backend contract", which involves the new TorchConversion (`torch_c`) dialect, which holds ops that need to operate on both the npcomp backend types (e.g. builtin tensors, i1, IREE list, etc.) and the `!torch` types. This made more sense, as I realized that if I didn't factor out `torch_c` then the Torch dialect would have a dependency on IREE dialect (we previously didn't notice this was an issue because we only depended on `builtin` types), which seemed wrong to me. Recommended review order: - TorchToIREE.cpp / `TorchToIREE/basic.mlir` - Look at the new structure of createTorchScriptToNpcompBackendPipeline. It now lives in TorchConversion/Transforms/Passes.cpp and cleanly calls into `Torch::createTorchScriptToTorchBackendPipeline` for the frontend lowering to the Torch backend contract. - Mechanical change extracting `torch_c.{to,from}_{i1,i64,f64,builtin_tensor,iree_list}` into a new TorchConversion dialect, and a few passes specific to the lowering from the Torch backend contract to the npcomp backend contract. - Minor fixes to TorchToLinalg.cpp to use unconverted operands (now that we convert lists as part of operand materialization, we need to use the original operands). Also added test for AtenMaxPool2dOp and fixed m_TorchConstantIntList. - TmpDeleteDeadIREELists pass. Temporary pass for deleting dead IREE lists that are created as part of operand materialization for conv/max pool/avg pool ops in TorchToLinalg.

This seems like a sweet spot subset of things that can be lowered directly to linalg, while not being overly constraining to users. This is consistent with what IREE is doing for CHLO->Linalg lowering as well ([code](https://github.com/google/iree/blob/50bf7a87e465d2048c527bc27724edde40519b7e/iree/compiler/InputConversion/MHLO/BroadcastingToLinalgPatterns.cpp#L1)). To test the static size-1 case, we added support for the `torch.aten.unsqueeze` op and lowering for it through `linalg.tensor_expand_shape`. This involved a generalization of `MaximizeValueSemantics` able to handle it (the solution there also works for `torch.aten.flatten.using_ints` which we need for ResNet anyway) Also, a few minor additional changes: - Add `VerifyInvariantsBeforeBackendLowering` pass, which catches a large class of errors before we get to backend lowering (now that we are doing dialect conversion, the errors are way nicer if we just emit them up front rather than in the guts of a random pattern). - Minor change to RefBackend to allow `linalg.tensor_expand_shape`. Recommended review order: - e2e tests in elementwise.py - `ConvertElementwiseOp` in TorchToLinalg.cpp + elementwise.mlir test - `ConvertAtenUnsqueezeOp` in TorchToLinalg.cpp + unsqueeze.mlir test - RefineTypes.cpp + tests - MaximizeValueSemantics changes + test - VerifyInvariantsBeforeBackendLowering pass + test

mlir: bump llvm tag to 5380e3 (#856) In addition to updating the llvm-project submodule, this patch also: 1. updates shape functions and tests so that `func` and `call` operations refer to the `func` dialect 2. avoid duplicate registration of dialects

linalg: lower `aten.triu` op to `linalg.generic` (#965) Prior to this patch, the torch dialect included `AtenTriuOp` for computing the upper triangular part of the input matrix, but there was no code for lowering the op to the linalg dialect. This patch adds code to generate a `linalg.generic` operation that compares indices (computed using `linalg.index`) to choose between zero or the original value (using `arith.select`). The lowering fails if the number of dimensions are less than two. This patch also adds a few end-to-end tests.
