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.
