[PATCH] [X86][SSE] psrl(w/d/q) and psll(w/d/q) bit shifts for SSE2

[Chandler Carruth]

This is much better, but I still think there is a simpler way to write the inner loops. Trying to explain this with prose isn't helping tjough, so I'll try to patch and modify it. If it works I can submit the hybrid result, and if not I'll understand much better why not. =]
