Yes, e.g. V4QI may be represented with SImode. But that's fine,
since the vectorizer may be able to optimize data movement loops
with no other vector support in the target. (E.g. if target and
destination are alignable.)
The real problem is that you're pulling out SImode and deciding
that add_optab[SImode] is the vector addition operation.
