Hi!
When looking at PR85090, I've looked into tmp-mddump.md and noticed there
some instructions that can't assemble - vblendmd etc., there is only
vpblendmd or vblendmps. I couldn't make a testcase that would reproduce
this though, seems the masked *mov<mode>_internal is used instead.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
