Thanks, Andi also asked me to support them ;)
As far as I can see, that requires more work to support
EVEX decoding. And perhaps, I have to classify new instructions
and operands and introduce new abbreviations/superscripts for
them, because there is no opcode map in the above document.

Would you intel guys have any idea about new opcode map?

Thank you,
