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

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.

- Introduce operations in a new lmhlo_gpu dialect that map to GPU library function calls
in the XLA:GPU backend.
- Add basic unit tests as well.

- Create a common class that hold ConvOp attributes that are common to MHLO and
LHLO Dialects and use Tablegen DAG concat to append these common attributes to
dialect specific arguments in ODS for ConvOp.

- 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.

- This causes declaration of reifyReturnTypeShapes to be inserted in the TableGen
generated code without explicitly adding it in extraClassDeclaration.

- Use MLIR provided constraints for HLO_ScalarIntTensor and HLO_DimensionTensor.
- Update unit tests to expect new error messages.

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.

Add `tan` op and lowering to CHLO dialect, move CHLO lowerings to
`chlo_legalize_to_hlo_patterns` and extend missing patterns.

Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/43137
This PR removes lhlo-copy-removal pass entirely and replace its usages with ```mlir::createCopyRemovalPass()```.
