updated patch

And there is also has_simduid_loops and loop->safelen and loop->force_vect.
Also loop->simduid but 1) I don't know how to stream it, 2) it seems to work
without.  But I see the vectorizer looks at DECL_UID (loop->simduid)), so
"work without" may mean it just doesn't vectorize the thing but cleans up.
