[PATCH] D26120: [Cortex-M0] Atomic lowering

[Weiming Zhao via llvm-commits]

weimingz added a comment.

Agree with the change in shouldExpandAtomicRMWInIR but for  ARMSubtarget::enableAtomicExpand(), 
changing from

  return hasAnyDataBarrier() && (!isThumb() || hasV8MBaselineOps()

to

  return hasAnyDataBarrier();

Is it too relax? Seems OK but not very sure.
