[PATCH] D52327: [Loop Vectorizer] Abandon vectorization when no integer IV found

If there's some actual implementation work involved in supporting it, fine, I guess... but it seems like it can't be much work to support properly: even just adding an unused i1 induction variable is enough to get around the crash for the given testcase.
