I can't spot any encoding change. Or wait - it's operand encoding which
changes for dupq and syntax which changes for extq.

I'm also unconvinced the insn adjustments should be folded with the 9.4-A
related adjustment.

But I'm not an Arm64 maintainer, so neither of my comments (nor anything
else I might have to say, if only the patch was supplied inline to make
it easy to comment) matters overly much anyway.
