If this is acceptable, I'm planning to add support for {,v}mov{a,u}p{s,d}
and {,v}movntp{s,d} (plus the respective opcode variants, even though
I think we only really need full width loads and stores for the next little
while) to deal with reports like in

Absolutely fine in principle. I'm only quibbling over details in your
current patch 2/2.
