Not those, but addvmode4 and subvmode4 instead (perhaps {,u}mulvmode4 if
the ISA detects multiplication overflows, also there is negvmode3).

Mul doesn't produce useful overflow bits when the flags are set. We could do
negv3.

That's what I meant. Still can't find any info on them in md.texi, though!
