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.

Smit Hinsu 4ef12aa000 Update GetDimensionSize and SetDimensionSize ops to use I64 attribute for dimension
This is to match with HLO semantics and general dimension semantics in MLIR.

Also,

* Define minimal verifier for these ops.
* Add folder for SetDimensionSize op on static shaped dimension.
* Fix assumption of ranked shape in GetDimensionSize op.

Tres Popp 76b30fd426 Move unranked chlo lowering to transform_unranked_hlo.
Additionally:
- Forward listeners through new if/else op builders.
This corrects an error that led to incomplete legalization of broadcasted op
lowering.
- Use OpConversionPattern to ensure up to date operand values are used.

Smit Hinsu 6eda9ed273 Add compare_type optional attribute to CompareOp in HLO dialects
If unspecified, `compare_type` is FLOAT for float element types, SIGNED for signed element types and UNSIGNED for unsigned element types. compare_type can be TOTALORDER for float element types.

- Added import and export support the attribute.
- Restricted legalization from HLO to TF to the default compare types.
- Updated existing usage of the CompareOp

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.

Mehdi Amini 7abd557a61 Add a header for table-gen generated pass for MHLO and use it in SinkConstantsToControlFlowPass
A non globally registered pass should define `getName()` in order to generate correct crash reproducers.
This is something we get "for free" when using the TableGen generated base class.
We should also migrate the other passes to the same mechanism and remove the static
global registration.
