        * tree-vectorizer.c (vect_get_base_and_offset): Call get_inner_reference
        and vect_analyze_offset_expr.
        (vect_create_addr_base_for_vector_ref): Build address_base by combining
        base and initial_offset fields of vect_stmt_info.
        (vect_update_inits_of_dr): Update offset of data-ref instead of its
        access-fn. Remove argument.
        (vect_update_inits_of_drs): Call vect_update_inits_of_dr with new
        arguments.
        (vect_compute_data_ref_alignment): Check misalignment info in
        vect_stmt_info. Remove argument.
        (vect_compute_data_refs_alignment): Call vect_compute_data_ref_alignment
        with correct argument.
        (vect_analyze_data_ref_access): Check access info in vect_stmt_info.
        (vect_analyze_pointer_ref_access): Update step and initial_offset fields
        of vect_stmt_info.
        (vect_get_memtag_and_dr): Call vect_get_base_and_offset and set the
        fields of stmt_vec_info.
        (vect_analyze_data_refs): Find vectype and pass it to
        vect_get_memtag_and_dr.
        (vect_get_first_index): Remove.
        (vect_compute_array_base_alignment): Remove.
        (vect_compute_array_ref_alignment): Remove
        (vect_create_data_ref_ptr): Use TYPE_SIZE_UNIT instead GET_MODE_SIZE.
        (vect_gen_niters_for_prolog_loop): Use TREE_CONSTANT instead
        host_integerp.
        (vectorizable_load): Use size arithmetics.
