SGTM. Sorry, I haven't been keeping up with this PR. Please wait for approval from others.

However, I'm wondering if these transformations could be moved to a different pass. I think that this isn't something SimplifyCFG should be handling. There's already quite a bit of similar code here. Of course, It's fine to merge this PR for me. :)
