tree-vectorizer.h (struct dr_with_seg_len): Remove class member OFFSET.
* tree-vectorizer.h (struct dr_with_seg_len): Remove class
member OFFSET.
* tree-vect-data-refs.c (operator ==): Handle DR_OFFSET directly,
rather than OFFSET.
(comp_dr_with_seg_len_pair): Ditto.
(vect_prune_runtime_alias_test_list): Ditto. Also Canonicalize
struct dr_with_seg_len_pair against DR_OFFSET.
* tree-vect-loop-manip.c (vect_create_cond_for_alias_checks): Handle
DR_OFFSET directly.
* gcc.dg/vect/vect-alias-check-1.c: New test.
