* tree-data-ref.c (dr_step_indicator): Handle NULL DR_STEP.
* tree-vect-data-refs.c (vect_analyze_possibly_independent_ddr):
Avoid calling vect_mark_for_runtime_alias_test with gathers or scatters.
(vect_analyze_data_ref_dependence): Re-order checks to deal with
NULL DR_STEP.
(vect_record_base_alignments): Do not record base alignment
for gathers or scatters.
(vect_compute_data_ref_alignment): Drop return value that is always
true. Bail out early for gathers or scatters.
(vect_enhance_data_refs_alignment): Bail out early for gathers
or scatters.
(vect_find_same_alignment_drs): Likewise.
(vect_analyze_data_refs_alignment): Remove dead code.
(vect_slp_analyze_and_verify_node_alignment): Likewise.
(vect_analyze_data_refs): For possible gathers or scatters do
not create an alternate DR, just check their possible validity
and mark them. Adjust DECL_NONALIASED handling to not rely
on DR_BASE_ADDRESS.
* tree-vect-loop-manip.c (vect_update_inits_of_drs): Do not
update inits of gathers or scatters.
* tree-vect-patterns.c (vect_recog_mask_conversion_pattern):
Also copy gather/scatter flag to pattern vinfo.
