[PATCH] D33105: [AMDGPU] Turn register pressure estimation into forward tracker

[Valery Pykhtin via Phabricator via llvm-commits]

vpykhtin added a comment.

If I don't mistake downward tracker cannot work on arbitrary instruction order, so let's change it's interface so that it tracks current instruction and move it, likewise like llvm standard tracker, that is reset(MI), advance()
