[PATCH] D83595: [Draft][MSAN] Optimize away poisoning allocas that are always written before load

[Gui Andrade via Phabricator via llvm-commits]

guiand added a comment.

I figured if it's using GEP then it's likely not going to be storing to the entire shadow. Bitcast is overwhelmingly common though (especially bitcast->lifetime.start, which I realize I need to handle).
