[PATCH] D87399: Revert "[InstCombine] erase instructions leading up to unreachable"

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

Admittedly, zapping stores (volatile or not) was not in the original motivation for the patch, but it seemed nice to see that enhancement. 
Reverting until things are sorted out is ok with me, but I agree with @nikic - since the LangRef is clear today about the behavior and that was hashed out on llvm-dev, somebody (not me) needs to rehash that on llvm-dev. Also, you'll need to reopen https://llvm.org/PR47416 and/or propose an alternate fix.
