x86: simplify decode of opcodes valid only without any (embedded) prefix
In this case there's no need to go through prefix_table[] at all - the
.prefix_requirement == PREFIX_OPCODE machinery takes care of this case
already.
A couple of further adjustments are needed though:
- Gv / Ev and alike then can't be used (needs to be Gdq / Edq instead),
- dq_mode and friends shouldn't lead to PREFIX_DATA getting set in
used_prefixes.
