[PATCH] D75341: [BFI] Use CallbackVH to notify BFI about deletion of basic blocks

davidxl added a comment.

I think we should explicitly fix the real problems that new blocks are not updated frequency information instead of just letting them get a known default value. Doing it later can make it harder to find those problems, right?
