GlobalISel: Revisit users of other merge opcodes in artifact combiner

The artifact combiner searches for the uses of G_MERGE_VALUES for
unmerge/trunc that need further combining. This also needs to handle
the vector merge opcodes the same way. This fixes leaving behind some
pairs I expected to be removed, that were if the legalizer is run a
second time.
