[PATCH] D22414: [BranchProbabilityInfo] Change analysis result storage to simplify basic block removal

Hi,

I don't have specific build times. This is mostly motivated by the review comments in the https://reviews.llvm.org/D20957. Evidence for importance of this is that LVI also had linear time EraseBlock and it caused problems there. BPI will call EraseBlock exactly as frequently as LVI did, so it's natural to assume that performance bottleneck will be in the same place.
