Chandler Carruth 05901d80ba [x86] Teach the new vector shuffle lowering a fancier way to lower ...

256-bit vectors with lane-crossing.

Rather than immediately decomposing to 128-bit vectors, try flipping the
256-bit vector lanes, shuffling them and blending them together. This
reduces our worst case shuffle by a pretty significant margin across the
board.
