[PATCH] D60679: [LowerAtomic] Lower fadd and fsub atomicrmw instructions

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

This still needs tests, but it seems this duplicate pass thing could use some work. Both passes have essentially the same switch to turn the atomic into the equivalent non-atomic. It seems to be me like AtomicExpandPass is a superset of LowerAtomic, except AtomicExpand seems to ignore fences
