        * tree-vect-analyze.c (vect_analyze_data_ref_dependence): DRs whose
        dependence-distance modulo VF is 0 are recorded in the
        SAME_ALIGN_REFs VEC in each DR.
        (vect_enhance_data_refs_alignment): Avoid 80 column overflow. The
        alignment information of DRs that are in the SAME_ALIGN_REFs VEC of the
        DR we want to peel for, is set to 0.
        * tree-vect-transform.c (vect_do_peeling_for_loop_bound): Fix printout.
        * tree-vectorizer.c (destroy_loop_vec_info): Free the SAME_ALIGN_REFs
        VEC.
        * tree-vectorizer.h (dr_p): New type. Defined to use the VEC API.
        (_stmt_vec_info): Added new field same_align_refs.
        (STMT_VINFO_SAME_ALIGN_REFS): New macro.
