[ARM] Set correct successors in CMPXCHG pseudo expansion.
transferSuccessors() would LoadCmpBB a successor of DoneBB, whereas
it should be a successor of the original MBB.
The testcase changes are caused by Thumb2SizeReduction, which
was previously confused by the broken CFG.
Follow-up to r266679.
Unfortunately, it's tricky to catch this in the verifier.
