stack slots and giving them different PseudoSourceValue's did not fix the

move above a store of spill slot #2 .

- added hasSSE4A
- updated AutoDetectSubtargetFeatures to detect SSE4A
- updated GetCurrentX86CPU to detect family 15 with sse3 as k8-sse3 and

New processor names match those used by gcc.
