Matt Arsenault 171cf5302f AMDGPU/GlobalISel: Handle flat/global G_ATOMIC_CMPXCHG 
Custom lower this to a target instruction with the merge operands. I
think it might be better to directly select this and emit a
REG_SEQUENCE, but this would be more work since it would require
splitting the tablegen patterns for these cases from the other
atomics.
