Unique Super Shuffle Engine

By implementing a full-width, single-pass shuffle unit that is 128-bits wide, Penryn processors can action full-width shuffles in a single cycle. This significantly improves action for SSE2, SSE3 and SSE4 instructions that have shuffle-like dealings much as pack, unpack and wider crowded shifts. This feature will increase action for noesis creation, imaging, recording and high-performance computing.
