Benjamin Kramer d1c60df2fe [MHLO:linalg] Be more aggressive about turning mhlo.const into std.constant
On tensors the only difference between these ops is that mhlo.const supports unsigned types.

Hanhan Wang 1ba4c714c9 Add support for lowering mhlo.scatter ops to Linalg.
This only works for updating tensors, not add/min/max computations. It requires
the index depth to be 1 because of the limitation in Linalg. We can not compare
multiple indices without packing indices.

Stella Laurenzo 71394fb301 Properly handle if DynamicBroadcastInDimOp shape is not of index type.
* The op defines this to be index, any integer, or pred (i1).
* Many TensorFlow legalizations produce integers for the shape.

Ben Vanik b06baae910 Fixing nondeterminism in pattern application.
The ReduceRegion* patterns are matching on the same ops as the PointwiseToLinalg*
patterns and on certain toolchains (MSVC) the order can be wrong. If the pointwise
runs first then it converts the op *within* the reduction before the reduction one
runs, leading to nested linalg op weirdness.

Benjamin Kramer f4414fcd66 [MHLO:Linalg] Add support for lowering unsigned ops
This strips away the signedness with a type converter, using unrealized
conversion casts. The rest is mostly mechanically pushing the original op down
the pipeline so lowerings can see the original types.

Signed types stay signless for now. This can be changed in the HLO bridge later.

I did a pass over all ops and added unsigned lowerings where they were missing.
There may be more.

Currently the lowering will die at a later stage because it doesn't understand
the unrealized casts.

Benjamin Kramer 4d435a817e [mhlo:linalg] Add support for lowering mhlo.concatenate to Linalg ops.
This uses a indexed linalg.generic, which is rather awkward standalone but
allows fusing into the output of the concatenate and avoid to ever materialize
it in memory. I think this is the only way to get that with the current linalg
stack, fusion across a concatenate would require more infrastructure.

Hanhan Wang c466f08993 Add checks in ReduceWindowOpOnTensorsConversion.
The pattern does not support ops with non-zero padding config. Add a check to
prevent unexpected lowering.

It is not easy to add tests because other patterns will convert body ops, and
it causes issues like invalid IRs.

Benjamin Kramer 59fa7c0ef7 [MHLO:linalg] Lower all dynamic broadcasts of static shapes to linalg.generic
We only need the memref_reinterpret_cast if we don't know whether a dimension
gets expanded or not. With static shapes we know that a dimension can only be
expanded if it's a static 1, so lower it in the same way we lower fully
static broadcasts.

Hanhan Wang 90f0d7f935 Add support for lowering mhlo.conv to Linalg on tensors.
This pattern only works for normal convolutions. It does not work for depthwise
convolutions. The Linalg conv ops are defined with static rank, so it only
supports 1d/2d/3d cases, which are the most typical cases.

This also refactors out the same check in lmhlo.conv lowering.
