[PATCH] D31124: AMDGPU/SI: Add lane tracking to SI Scheduler

[Valery Pykhtin via Phabricator via llvm-commits]

In general, I think moving instructions just to use standard RP tracker to discover liveins/liveouts isn't a good idea. It isn't only slow but doesn't look reliable too. Why not discover these sets using DAG directly?
