Bruno Cardoso Lopes 8830fde434 The vpermilps and vpermilpd have different behaviour regarding the
usage of the shuffle bitmask. Both work in 128-bit lanes without
crossing, but in the former the mask of the high part is the same
used by the low part while in the later both lanes have independent
masks. Handle this properly and and add support for vpermilpd.
