I agree with Paul that we can remove the opcode check; I have a vague memory of
looking for a helper function to determine whether the mask was all-true (or
better, whether the ptest was redundant), not finding one, and just sticking a
check for PTRUE in to get my tests up and running. Sadly I didn't revisit that
before committing.
