Simon Pilgrim a5a17c0b23 [X86][SSE] Use (V)PINSRB for direct byte insertion in 16i8 buildvector on SSE4.1 targets 
This patch allows SSE4.1 targets to use (V)PINSRB to create 16i8 vectors by inserting i8 scalars directly into a XMM register instead of merging pairs of i8 scalars into a i16 and using the SSE2 PINSRW instruction.

This allows folding of byte loads and reduces scalar register usage as well.
