* tree-vectorizer.c (vect_get_base_and_offset): Remove.
        (vect_is_simple_iv_evolution): Remove redundant parameter
        and step check.
        (vect_analyze_scalar_cycles): Call vect_is_simple_iv_evolution
        without last parameter.
        (vect_analyze_pointer_ref_access): Get access_fn as parameter.
        Return pointer step. Call vect_is_simple_iv_evolution without
        last parameter. Check only that the step is multiple of size
        type. Remove stmt_vinfo updates.
        (vect_get_memtag_and_dr): Remove.
        (vect_get_memtag): New function.
        (vect_address_analysis): New function.
        (vect_object_analysis): New function.
        (vect_analyze_data_refs): Call vect_object_analysis and
        vect_get_memtag. Update stmt_vinfo fields.
