[PATCH] D76332: Fix MSan false positive due to select folding.

Interesting. Poison semantics are very similar to MemorySanitizer model.
Should I remove TryToUnfoldSelectInCurrBB completely? I don't see how it can be saved.
Am I right about the other two instances of select folding in this pass being safe? They insert new conditional branches only on code paths that already had a branch with the same condition.
