@xur-llvm this might cause compile time issues during PGOUse if you have a profiled function with a large number of critical edges. But after https://reviews.llvm.org/D137184 you should no longer get profiles for those functions. If you have profiles that haven't been updated I think we can move the `PGOFunctionCriticalEdgeThreshold` logic out of `skipPGO()` so that it can be used for both PGOGen and PGOUse.
