[PATCH] D21674: [BranchFolding] Update UnavoidableBlocks for OutlineOptionalBranches

[Kyle Butt via llvm-commits]

iteratee added a comment.

I'm also looking at this, and it doesn't even correctly update the list of unavoidable blocks. Consider merging 2 identical blocks, neither of which is unavoidable, but the merged block is. There are other examples, but that's probably the simplest one to describe in a comment.
