tree-optimization/101505 - properly determine stmt precision for PHIs

Loop vectorization pattern recog fails to walk PHIs when determining
stmt precisions.  This fails to recognize non-mask uses for bools
in PHIs and outer loop vectorization.

PR tree-optimization/101505
* tree-vect-patterns.c (vect_determine_precisions): Walk
PHIs also for loop vectorization.

* gcc.dg/vect/pr101505.c: New testcase.
