[PATCH] D109031: [AMDGPU] Introduce optimizeCompareInstr

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

I probably also want to invert the logic, remove the threshold, check for vreg def and scan to def. Even without threshold it is probably faster since looking for def is O(1) and most of the cases will be rejected just by looking at def.
