Thanks! I think I was able to isolate the bits that caused problems:

1. Unecessarily looking through selects outside the loop
2. Introducing branches on undef/poison when looking through selects.

I recommitted the change in e9cced27390ba38eac1144aa1240281a1edadec0 <https://reviews.llvm.org/rGe9cced27390ba38eac1144aa1240281a1edadec0>. I couldn't test with msan though, as it's not available on macOS. Please let me know if you see further issues.
