CGProfile.cpp is a no-op if no function provides > `getEntryFreq()`. It's a functional no-op, but it runs the BFI analysis, which as Nikita pointed out above adds some compile-time cost. Not scheduling the pass unless we're using profile info seems like a reasonable way to avoid that cost to me. The alternative of using LazyBlockFrequencyInfoPass and checking PSI->hasProfileSummary() first would also work I guess. If you think that's cleaner, maybe that's the better way to go.
