[PATCH] D12781: PGO IR-level instrumentation infrastructure

[Kostya Serebryany via llvm-commits]

kcc added a comment.

\> - is there a reason that this is breaking critical edges itself instead of using break-crit-edges pass? Is break-crit-edges dead? SanitizerCoverage doesn't seem to use it either.

SanitizerCoverage uses SplitAllCriticalEdges from include/llvm/Transforms/Utils/BasicBlockUtils.h
