Valery Pykhtin c59c19bf59 [MachineSSAUpdater][AMDGPU] Add faster version of MachineSSAUpdater class. (#145722) ...

This is a port of SSAUpdaterBulk to machine IR minus "bulk" part. Phi
deduplication and simplification are not yet implemented but can be
added if needed.

When used in AMDGPU to replace MachineSSAUpdater for i1 copy lowering,
it reduced compilation time from 417 to 180 seconds for the pass on a
large test case (56% improvement).
