Hm, I think this is a general and/or target issue. We treat vector
compares as possibly trapping (similar to scalar fp compares).
What is new since 4.7 is that we can produce vector compares that
may throw at the gimple level. The vectorizer will not create them
and intrinsics are not marked as possibly throwing.
