1023ddaf77 [LLVM] Add the support for fmax and fmin in atomicrmw instruction 
This patch adds the support for `fmax` and `fmin` operations in `atomicrmw`
instruction. For now (at least in this patch), the instruction will be expanded
to CAS loop. There are already a couple of targets supporting the feature. I'll
create another patch(es) to enable them accordingly.

39f1568633 Transforms: Split LowerAtomics into separate Utils and pass 
This will allow code sharing from AtomicExpandPass. Not entirely sure
why these exist as separate passes though.
