[MLIR] CtPop and BitReverse in LLVMIR and Standard (with lowering), and Cttz in LLVMIR
Changes PlannedPublic

Authored by shawnl on Jul 8 2020, 8:20 AM.



Implement and test CtPop and BitReverse in standard, with lowering to LLVM. Test LLVM's cttz.

The cttz lowering is a bit tricky, as the second argument must be set to i1 0,
so that waits until later.
