A. Unique TensorFlower c217a6ef61 [MHLO] Add pass to move up dynamic broadcasts for fusion
For now, the pass only reifies the required shape computations. Moving
broadcasts will follow to allow for fusion across them.

Jacques Pienaar 329b1fd071 Verify compatible shapes in unpack verification rather than exact
Previously this would be too strict and fail if dynamic and static dims were
compared. Dynamic/unknown are treated as "maybe equal" to a static value without further info, so at this layer don't flag as invalid unless truly are.

Adrian Kuegel e6a1f5f0f9 Add MinimumBroadcastShapesOp to chlo dialect.
This op is useful for rank specialization of broadcasts. Kernel Generator
needs to generate one kernel for each rank, so if we can minimize the rank
of the broadcast shape, we can support more cases with the same number of
special-cased kernels.

Rahul Joshi 0da7ea2545 [MLIR][HLO] Cleanup CMakeLists and comments.
- Cleanup CMakeLists file to remove unused argument and use a new function for
  setting up lmhlo and lmhlo_gpu dialect targets.
- Fix inconsistently formatted copyright comment and fix header include guards.

Rahul Joshi 5adb7c6e12 [MLIR:LHLO] Add optional call target arg mapping to LMHLO CustomCall operations.
- XLA:HLO -> LMHLO conversion drops all token arguments and return values, however
  custom calls that users write still expect to get buffer pointers for these token types.
- To be able to support this, add an optional call target argument mapping attribute to
  LMHLO custom calls. When this attribute is present, it indicates the number of
  arguments and returns that the custom call expects and also indicates which LMHLO
  arg() or output() maps to which arg or result number of the custom call.

Prakalp Srivastava 909574e393 Pass result element type to XlaBuilder for `mhlo.dot_general` and `mhlo.convolution` ops.
`mhlo.dot_general` and `mhlo.convolution` result element type might be different from operand element type. See `preferred_element_type` attribute that allows i8xi8 to i32 dot computation. `mhlo` to HLO exporter should pass the result element type to Xla builder to override the shape inference of XLA.
