Hi,
This patch fixes the bug when comparing location to UNKNOWN_LOC.
Bootstrapped and passed gcc regression test.
Okay for trunk?
Thanks,

* gcc/tree-vect-loop-manip.c (slpeel_make_loop_iterate_ntimes): Use
LOCATION_LOCUS to compare with UNKNOWN_LOCATION.
(slpeel_tree_peel_loop_to_edge): Likewise.
* gcc/tree-vectorizer.c (vectorize_loops): Likewise.
