x86: correct operand type checks
Again these look to be typos: No template currently allows for any two
(or all three) of RegXMM, RegYMM, and RegZMM in a single operand. Quite
clearly ! are missing, after the addition of which the checks for the
first and (if present) second operands also fully match up.
