  Log Message:
  -----------
  [ARM] Add errors for MVE exclusive registers.

These instructions already had errors for operands that could not share
the same register:
  VCMUL, VMULL, VQDMULL.
This extends that to a few others:
  VREV64, VQDMULLqr, VCADD and VHCADD.
Only the i32 types require the error.
