all: VPCLMULQDQ instruction (#360)

Browse Source 
Adds VEX and EVEX encoded versions of the `PCLMULQDQ` carry-less quadword
multiplication instruction.

These are added via the `opcodesextra` mechanism #345, since they're missing
from the opcodes database.

Contributed by @vsivsi. Extracted from #349 with minor tweaks.
