Simon Pilgrim 44513da617 [X86][SSE] Float comparisons can sometimes be safely commuted 
For ordered, unordered, equal and not-equal tests, packed float and double comparison instructions can be safely commuted without affecting the results. This patch checks the comparison mode of the (v)cmpps + (v)cmppd instructions and commutes the result if it can.
