Rahul Joshi 1958f228ec [MLIR:HLO] Extend CustomCall to support multiple outputs.
- Extend MHLO CustomCall to have multiple tensors as results.
- Extend LHLO CustomCall to have multiple memrefs for output operands.
- Fix HLO->LHLO and XLA HLO->LHLO mapping for CustomCall to setup the
  operand_segment_sizes attribute correctly.

Alexander Belyaev d4f2c767d3 [HLO] Fix HLO DynamicBroadcastInDimOp -> LHLO lowering.
The conversion had a bug in computation of strides and sizes args for std.memref_reinterpret_cast. The previous version also relied on linalg::ReshapeOp to do broadcasting when the rank of the output was higher than the rank of the input. Now the broadcasting is entirely done via descriptor modification and linalg::ReshapeOp was replaced with CopyOp.

A. Unique TensorFlower 33c450e4cb Fix the MHLO to LMHLO lowering of 'gather'
The lowering assumes that the 'gather' op attributes are identical in both MHLO and LMHLO. But that's not true; some time ago the MHLO version was changed to pack 4 of its attributes into a struct. By doing the same for the LMHLO version we both fix the lowering for this op and resolve a longstanding TODO.

Rahul Joshi bce128b070 Introduce CustomCall operation in LHLO Dialect
- And add conversion from MHLO CustomCall to LHLO CustomCall
- According to XLA documentation, the called function should not be side effecting,
  so marking the argument MemRefs as MemRead.

Ehsan Toosi d599485e06 PR #43069: [hlo] Unbreak hlo-legalize-to-lhlo test
Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/43069

The legalization of mlhlo.ReturnOp to lhlo.TerminatorOp by using BufferAssignmentReturnOpConverter fails since the Memref typed results (or the Memref typed operands of Return operation) are set to stay as results after legalization but lhlo.TerminatorOp doesn't accept any operands. Therefore, BufferAssignmentReturnOpConverter must be replaced with a manual conversion that removes all operands of mlhlo.ReturnOp and inserts copy operations in their places.

Stephan Herhut c44e08351d Fix mhlo to lmhlo conversion for ReduceOp.
The existing conversion no longer worked and was not save to undo. Furthermore, the pattern for mhlo.return had been removed.

Also adds some tests to ensure this does not degrade again.

and depend only on MLIR.
