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.

Marius Brehler ff9b8c6f65 PR #44499: Add missing dep on MLIRMhloPassIncGen target 
Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/44499

The file `sink_constants_to_control_flow.cc` includes the header
`PassDetail.h`, which itself includes `mhlo_passes.h.inc`. The latter is
not guaranteed to be already generated since there was no dependency set
to MLIRMhloPassIncGen.

Jacques Pienaar 344c500fca [mhlo] Add legalize to SCF pass 
Start of pass to legalize MHLO control flow to SCF for further optimization in common form. The current version just matches a very simple instance (which also happens to occur a few times). Exposes some further canonicalization opportunities that aren't yet addressed.
