Jeffrey Byrnes 7f0a881e6c [AMDGPU] Track liveins for max-ilp-sched-strategy ...

Even if optimizing for ILP, it is still useful to track RP to avoid spilling. Given that, we need to maintin consistent liveness state with the RP tracker. This patch makes RP tracking consistent by updating for liveins.

Otherwise, we should completely eliminate RP tracking for this scheduler (checkScheduling, initCandidate).
