Evan Cheng bbc726d624 Fix a minor bug in two-address pass. It was missing a commute opportunity. 
regB = move RCX
regA = op regB, regC
RAX  = move regA
where both regB and regC are killed. If regB is constrainted to non-compatible
physical registers but regC is not constrainted at all, then it's better to
commute the instruction.
