Fix for incorrect parse of PEXTRW instruction

The instruction PEXTRW encoded by sequence 66 0F C5 has form:
PEXTRW reg, xmm, imm8. Its reg is encoded in the REG part and
xmm is encoded in the R/M part of ModR/M byte. Since the order
is opposite to the PEXTRB and PEXTRD, we have to set 'load' to
true and 'store' leave as false.
