pan/bi: Model MKVEC.v2i8

Valhall does not have Bifrost's 4-source MKVEC.v4i8. Instead, it has a (somewhat
limtied) 3-source MKVEC.v2i8. The full MKVEC.v4i8 may be lowered to a pair of
MKVEC.v2i8 instructions.

For good code quality on both Bifrost and Valhall, we need to model both
instructions in their full generality.
