You are right, with -O3 -fno-trapping-math already r151206 ICEs (haven't
bisected it down though).
If the vcond* condition on all targets just returned 0 for codes it doesn't
support, the vectorizer would need to create dummy RTL arguments in
expand_vec_cond_expr_p. But perhaps that's still better than adding yet
another iterator to vcond, then it would iterate on 3 iterators...
