Simon Pilgrim 3f1d66fe93 [X86][SSE] Vector integer to float conversion memory folding
Added missing memory folding for the (V)CVTDQ2PS instructions - we can safely fold these (but not the (V)CVTDQ2PD versions which have a register/memory size discrepancy in the source operand). I've added a test case demonstrating that stack folding now works.
