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

[Daniil Suchkov via Phabricator via llvm-commits]

DaniilSuchkov added a comment.

One thing I don't understand is why three out of four kinds of VHs perform the const_cast, not the ValueHandleBase. I think it's time to change that (and by doing so, allow CallbackVH accept const pointers too).
