rewrite 0f-based instruction handling
this is... a more significant rewrite than i expected yaxpeax-x86 to
ever need. it turns out that capstone is extremely permissive about
duplicative 66/f2/f3 prefixes to the point that the implemented prefex
handling was unsalvageable.
while this replaces the *0f* opcode tables, i haven't profiled these
changes. it's possible this is a net improvement for single-byte
opcodes, it could be a net loss. code size may be severely impacted.
there is still work to do.
but this in total gets very close to iced/xed/zydis parity, far more
than before.
also adds several small extensions, gfni, 3dnow, enqcmd, invpcid, some
of cet, and a few missing avx instructions.
