Fix nonconforming memory_operand for vpmovq{d,w,b}/vpmovd{w,b}/vpmovwb.

Fix nonconforming memory_operand for vpmovq{d,w,b}/vpmovd{w,b}/vpmovwb.

According to Intel SDM, VPMOVQB xmm1/m16 {k1}{z}, xmm2 has 16-bit
memory_operand instead of 128-bit one which existed in current
implementation. Also for other vpmov instructions which have
memory_operand narrower than 128bits.
