Added RegionBranchOpInterfaces to lmhlo operations that use regions.
This is needed, since the bufferization features in MLIR have to reason about the control flow within these operations.

These targets are now identical as all registration is explicit.
Temporarily leaving the old target as a (deprecated) alias while
changes propagate.

- Extract verification of source target pairs attached to collective permute into a common
helper function and use that to verify both MHLO and LMHLO variants.
- Change MlirGpuTestBase::ParseMlirModule to allow returning back a failure, and use
that to update the mlir_gpu_compile_test to check the new behavior.

For now, the pass only reifies the required shape computations. Moving
broadcasts will follow to allow for fusion across them.

- 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.

This is the preferred name for the Bazel repository when included from
another project.
Note: These hardcoded "external/" includes are a horrible hack that we
can hopefully get rid of soon with more robust Bazel tablegen rules.

For floating point operations, this uses std.pow.
For integer operations, this lowers to a loop.
This adds a dependency on scf.
