[DAGCombiner] Don't let scalarizeBinOpOfSplats create illegal scalar MULHS/MULHU (#104518)
Type legalization lacks generic support for these operations. They are
normally only created when the type is legal. This scalarization case is
new.
We could update type legalization, but there some corner cases that make
it not straightforward. For example, if the promoted type isn't 2x the
narrow type we need to over promote.
Fixes #104480
