    M llvm/test/Transforms/InstCombine/atomicrmw.ll

  Log Message:
  -----------
  [InstCombine] Preserve alignment in atomicrmw -> store fold

Preserve the alignment of the original atomicrmw, rather than using
the ABI alignment.

The same problem exists for loads, but that code is being removed
in D141277 anyway.
