[TorchToLinalg] perform rank0 elementwise computations outside linalg generic ops (#3762)
This is motivated by the fact that shapes are stored as tensors in ONNX,
and IREE tries to perform tensor arithmetic on the device. This causes
unnecessary dispatches, and makes it harder for the compiler to reason
about shapes.

Here is a small snippet of torch-IR that is typical seen coming from
ONNX models:

```mlir
module {
  func.func @main_graph(%arg0: !torch.vtensor<[?,?,768],f32>, %arg1: !torch.vtensor<[?,?,768],f32>) -> !torch.vtensor<[],si64> {
    %int0 = torch.constant.int 0
    %0 = torch.vtensor.literal(dense<0> : tensor<1xsi64>) : !torch.vtensor<[1],si64>
    %1 = torch.aten._shape_as_tensor %arg1 : !torch.vtensor<[?,?,768],f32> -> !torch.vtensor<[3],si64>
    %2 = torch.aten.index_select %1, %int0, %0 : !torch.vtensor<[3],si64>, !torch.int, !torch.vtensor<[1],si64> -> !torch.vtensor<[1],si64>
    %3 = torch.aten.squeeze.dim %2, %int0 : !torch.vtensor<[1],si64>, !torch.int -> !torch.vtensor<[],si64>
    %4 = torch.aten.item %3 : !torch.vtensor<[],si64> -> !torch.int
    %5 = torch.aten.eq.int %4, %int0 : !torch.int, !torch.int -> !torch.bool
    %6 = torch.aten.Int.bool %5 : !torch.bool -> !torch.int
    %7 = torch.aten.size.int %arg0, %int0 : !torch.vtensor<[?,?,768],f32>, !torch.int -> !torch.int
    %8 = torch.prim.NumToTensor.Scalar %6 : !torch.int -> !torch.vtensor<[],i1>
    %9 = torch.prim.NumToTensor.Scalar %7 : !torch.int -> !torch.vtensor<[],si64>
    %10 = torch.prim.NumToTensor.Scalar %4 : !torch.int -> !torch.vtensor<[],si64>
    %11 = torch.aten.where.self %8, %9, %10 : !torch.vtensor<[],i1>, !torch.vtensor<[],si64>, !torch.vtensor<[],si64> -> !torch.vtensor<[],si64>
    return %11 : !torch.vtensor<[],si64>
  }
}
```

Without the change in this PR, the result would be:

```mlir
#map = affine_map<() -> ()>
module {
  ml_program.global private mutable @global_seed(dense<0> : tensor<i64>) : tensor<i64>
  func.func @main_graph(%arg0: tensor<?x?x768xf32>, %arg1: tensor<?x?x768xf32>) -> tensor<i64> {
    %c0_i64 = arith.constant 0 : i64
    %c0 = arith.constant 0 : index
    %dim = tensor.dim %arg1, %c0 : tensor<?x?x768xf32>
    %0 = arith.index_cast %dim : index to i64
    %1 = tensor.empty() : tensor<1xi64>
    %collapsed = tensor.collapse_shape %1 [] : tensor<1xi64> into tensor<i64>
    %2 = linalg.fill ins(%0 : i64) outs(%collapsed : tensor<i64>) -> tensor<i64>
    %extracted = tensor.extract %2[] : tensor<i64>
    %3 = arith.cmpi eq, %extracted, %c0_i64 : i64
    %dim_0 = tensor.dim %arg0, %c0 : tensor<?x?x768xf32>
    %4 = arith.index_cast %dim_0 : index to i64
    %5 = tensor.empty() : tensor<i1>
    %6 = linalg.fill ins(%3 : i1) outs(%5 : tensor<i1>) -> tensor<i1>
    %7 = tensor.empty() : tensor<i64>
    %8 = linalg.fill ins(%4 : i64) outs(%7 : tensor<i64>) -> tensor<i64>
    %9 = linalg.fill ins(%extracted : i64) outs(%7 : tensor<i64>) -> tensor<i64>
    %10 = linalg.generic {indexing_maps = [#map, #map, #map, #map], iterator_types = []} ins(%6, %8, %9 : tensor<i1>, tensor<i64>, tensor<i64>) outs(%7 : tensor<i64>) {
    ^bb0(%in: i1, %in_1: i64, %in_2: i64, %out: i64):
      %11 = arith.select %in, %in_1, %in_2 : i64
      linalg.yield %11 : i64
    } -> tensor<i64>
    return %10 : tensor<i64>
  }
}
```

With the change in this PR, we would instead get:

```mlir

  ml_program.global private mutable @global_seed(dense<0> : tensor<i64>) : tensor<i64>
  func.func @main_graph(%arg0: tensor<?x?x768xf32>, %arg1: tensor<?x?x768xf32>) -> tensor<i64> {

    %0 = arith.index_cast %dim : index to i64
    %1 = tensor.empty() : tensor<1xi64>
    %collapsed = tensor.collapse_shape %1 [] : tensor<1xi64> into tensor<i64>

    %7 = linalg.fill ins(%5 : i64) outs(%6 : tensor<i64>) -> tensor<i64>

[ONNX] simplify shapes fed to broadcast in Expand lowering (#3756)
Addresses ~200 onnx model compile failures in
<https://github.com/nod-ai/SHARK-TestSuite> related to
<https://github.com/iree-org/iree/issues/18631>.

This change simplifies the result of the generated broadcast op
substantially, but reduces the case coverage slightly.

The case which will become unsupported: 
- trying to actually broadcast a dynamic dim that is secretly 1. 

When does this case appear in practical scenarios?
- for a model where onnx shape inference cannot figure out that a dim
should be 1.

Why do I think we should not support this case for now?
1. For all models with dynamic dim expand ops, the previous path
uniformly generates uglier linalg IR (making it harder for IREE to fuse
properly with other ops).
2. For models failing shape inference castastrophically enough to fail
to see a dim is statically 1, we can try to apply constant folding in
the onnx model before importing.

Leaving this as a draft PR, since it may be more appropriate to fix the
compilation failure in IREE rather than torch-mlir.

### Example of broadcast required in previous path:

```mlir
    %300 = linalg.generic {indexing_maps = [#map11], iterator_types = ["parallel", "parallel", "parallel", "parallel"]} outs(%299 : tensor<?x12x?x?xi1>) {
    ^bb0(%out: i1):
      %306 = linalg.index 0 : index
      %307 = linalg.index 3 : index
      %308 = arith.index_cast %285 : i64 to index
      %309 = arith.cmpi eq, %308, %c1 : index
      %310 = arith.select %309, %c0, %306 : index
      %311 = arith.index_cast %286 : i64 to index
      %312 = arith.cmpi eq, %311, %c1 : index
      %313 = arith.select %312, %c0, %307 : index
      %extracted_79 = tensor.extract %reshape_78[%310, %c0, %c0, %313] : tensor<?x1x1x?xi1>
      linalg.yield %extracted_79 : i1
    } -> tensor<?x12x?x?xi1>
```

### Example of broadcast with simplified shape list:

```mlir
    %409 = linalg.generic {indexing_maps = [#map15, #map11], iterator_types = ["parallel", "parallel", "parallel", "parallel"]} ins(%reshape_135 : tensor<?x1x1x?xi1>) outs(%408 : tensor<?x12x?x?xi1>) {
    ^bb0(%in: i1, %out: i1):
      linalg.yield %in : i1
    } -> tensor<?x12x?x?xi1>
```

[Release] Fix binary name for downstream compatibility (#3752)
As of Sep 14, the torch-mlir binary
[wheels](https://github.com/llvm/torch-mlir-release/releases/tag/dev-wheels)
got renamed to `torch-mlir-core` from `torch-mlir`:
![image](https://github.com/user-attachments/assets/152e4977-71ef-4f57-8757-6dc75f72b670)

This was an unintended side-effect of the recent change of
`TORCH_MLIR_ENABLE_ONLY_MLIR_PYTHON_BINDINGS=True`
(https://github.com/llvm/torch-mlir/pull/3711) which skips setting `NAME
= "torch-mlir"` in
[setup.py](https://github.com/llvm/torch-mlir/blob/main/setup.py#L226-L232).

To avoid having multiple downstreams fix their pip deps, this change
allows using the same `torch-mlir` name for binaries, and reserves a
separate `torch-mlir-ext` name for the (less popular) binaries with
extensions enabled.

Vinayak Dev 67732883fa
[torch] Fix unsqueezed output shape in canonicalization of AtenUnflattenIntOp (#3730)
Fixes https://github.com/iree-org/iree/issues/18562.

During canonicalization pass on `AtenUnflattenIntOp`, if the second dim
was statically equal to one, we would create an `AtenAddIntOp` to add
one to the dimension obtained from `op.getDim()`. This, when passed into
`Torch::unsqueezeTensor()`, would make it get interpreted as
non-constant, which would lead to MLIR failing an assertion when
`UnsqueezeOp` would later get lowered into `ExpandShapeOp`, as the
output of the `UnsqueezeOp` would consist of only dynamic dims.

This patch fixes this behavior, by extracting the integer value from the
dim if it was constant, and then emitting a `ConstantIntOp` from
(dim+1). This creates an output with static shape.

[ONNX] Fix issue with absent value in onnx.ConstantOfShape (#3713)
Previously, if the value was absent, this conversion was creating a
dense resource of value 0 with shape equal to the result shape, then
later re-extracting a splat value. This only works if the shape is
statically known, and even when the shape is known, this is completely
unnecessary since the value's shape should be `[1]` and not the result
shape.

This patch simply sets the `splatvalue` to a `torch.constant.float 0.0`
when the onnx op's `value` attr is absent, and adds `nullptr` checks to
the subsequent conditionals to avoid them in the case where an `attr` is
not given.

[Torch] [TMTensor] Added mask and is_causal support for torch.aten.scaled_dot_product_attention (#3690)
Enabled mask and is_causal parameters for torch.aten.scaled_dot_product
attention + relevant comments + tests.

The tests added highlight the new capabilities introduced in this PR,
including:

Attention with F16 mask
Attention with Boolean mask
Causal attention with same Q K V shapes
Causal attention without Q K V shapes

Made sure that one cannot input both mask and is_causal.

Decompose aten.fmod into aten.mul,sub,div etc. (#3689)
As titled, create a new decomposition for `aten.fmod.Tensor` to
`aten.div`, `aten.trunc`, `aten.mul` and `aten.sub`. Note that we only
use `aten.trunc` for floating point operations. This further gets
decomposed to `aten.where` etc. by other existing decompositions.

This decomposition now makes TOSA pass for a simple model with
`aten.fmod` while it makes `stablehlo` fail. For now, we disallow this
decomposition for `stablehlo`

[TorchToLinalg] Use `linalg.transpose` instead of `generic` when lowering `aten.T` (#3660)
The lowering pattern for `aten.T` uses transposition implemented via
`linalg.generic`. For downstream passes it is advantageous to use named
ops wherever possible, so this patch changes the lowering to use
`linalg.transpose` instead.

Add a canonicalization pattern for `aten.unflatten.int` (#3656)
Addresses an issue in <https://github.com/llvm/torch-mlir/issues/3651>
where some unflatten ops generated from onnx models weren't propagating
static shape information. It may be necessary to add further
optimizations for the more general case when some static information is
present in the unflatten (or possibly reshape/view) op's `sizes` list,
but not reflected in the output shape. These ops will only successfully
infer shapes if the `sizes` list is gotten from a list of constant ints
(with possibly one -1). A common example where this fails is when some
of the `sizes` are determined from `aten.size.int` ops on dynamic
tensors, and other `sizes` are known statically.

This PR includes:
- a canonicalizer for `aten.unflatten.int` which converts to
`aten.unsqueeze` when it is expanding one dim to two, and one of the new
dims is statically 1.
- an improvement to the folder for `aten.__or__.bool` which does not
rely on *both* operands being static.

[fximporter] Avoid importing from `_torchMlir` (#3685)
Downstream projects don't necessarily register this C++ module. This
package removes the dependency and uses `torch.iinfo` to access the max
and min values instead.

Add canonicalize pattern for aten.mul.int and aten.floordiv.int (#3680)
This PR add `floordiv` to the `PY_BUILTIN_TO_TORCH_OP`. For
`aten.mul.int` and `aten.floordiv.int` ops, we add new Canonicalization
Patterns as follow:

```
%1 = torch.aten.mul.int %input, %const-5
%2 = torch.aten.mul.int %1, %const-6
```

Will be replaced by

`torch.aten.mul.int %input, %const-30`


And 

```
%1 = torch.aten.mul.int %input, %const-5
%2 = torch.aten.floordiv.int %1, %const-5
```
Will directly return `%input`


This PR also relaxes the `float` type constraint in TorchToTosa for the
`AtenRsubScalarOp` conversion.

`cmake --build build --target check-torch-mlir-all`
