[PATCH] Fix PR91114


The following fixes PR91114.  It's not really the most desirable
solution but hey.

Bootstrapped / tested on x86_64-unknown-linux-gnu, applied to trunk.

Richard.

2019-07-09  Richard Biener  <rguenther@suse.de>

	PR tree-optimization/91114
	* tree-vect-data-refs.c (vect_analyze_data_refs): Failure to
	find a vector type isn't fatal.

	* gcc.dg/vect/pr91114.c: New testcase.
