* tree-vectorizer.h (struct dr_with_seg_len): Remove the base
address field as it can be obtained from dr. Rename the struct.
* tree-vect-data-refs.c (comp_dr_with_seg_len_pair): Consider
steps of data references during sort.
(vect_prune_runtime_alias_test_list): Adjust with the change to
struct dr_with_seg_len.
* tree-vect-loop-manip.c (vect_create_cond_for_alias_checks):
Adjust with the change to struct dr_with_seg_len.

* gcc.dg/vect/vect-alias-check.c: Update.
