[PATCH] D50233: [InstCombine] Transform str(n)cmp to memcmp

[Eli Friedman via Phabricator via llvm-commits]

If it were just msan, I would say we could just check for the msan attribute and call it done.  But I'm a little worried about the potential race and potential weird interactions with LTO.  So probably best to both bailout if msan is enabled, and move the transform to expandmemcmp.
