a07ace61 - [AMDGPU][NFC] Extract GCNDownwardRPTracker::retireVirtReg (#228289)

[AMDGPU][NFC] Extract GCNDownwardRPTracker::retireVirtReg (#228289) Pull the per-register retirement logic out of advanceBeforeNext() into a helper. The operand reference is replaced by the register argument. A follow-up change needs to retire dying uses and dead defs at different points in the walk, which requires this logic to be callable from more than one place. https://github.com/llvm/llvm-project/pull/228294 depends on this patch.
