Ah, yes - we're not trying to do anything special if the mask and arg mask
types have different size - we can handle different number of lanes but we
don't
try any widening/shortening tricks to make the size match.
That said, it looks like we definitely should verify in the vectorizer that
we can handle the VEC_COND_EXPR.
As of trick missing, we could do v4si ? v4sf : v4sf and then widen to v4df
or widen v4si to v4di. Possibly the target could know what's more efficient
here.
Mine for adding the missing support check.
