[PATCH] [X86][SSE] Shuffle mask decode support for zero extend, scalar float/double moves and integer load instructions

[Simon Pilgrim]

Hi chandlerc, qcolombet, andreadb, spatel,

This patch adds shuffle mask decodes for integer zero extends (pmovzx** and movq xmm,xmm) and scalar float/double loads/moves (movss/movsd).

Also adds shuffle mask decodes for integer loads (movd/movq).
