Simon Pilgrim 5fa0fb23ca [X86][SSE] Missing SSE/AVX1 memory folding integer instructions 
Added most of the missing integer vector folding patterns for SSE (to SSE42) and AVX1.

The most useful of these are probably the i32/i64 extraction, i8/i16/i32/i64 insertions, zero/sign extension, unsigned saturation subtractions, i64 subtractions and the variable mask blends (pblendvb) - others include CLMUL, SSE42 string comparisons and bit tests.

Simon Pilgrim 0177fa3d8c [X86][SSE] Added SSE/AVX1 integer stack folding tests. 
Some folding patterns + tests are missing (marked as TODO) - these will be added in a future patch for review.
