        * tree-if-conv.c: Include builtins.h.
        (predicate_mem_writes): Put result of get_object_alignment (ref)
        into second argument's value.
        * tree-vect-stmts.c (vectorizable_mask_load_store): Put minimum
        pointer alignment into second argument's value.
        * tree-data-ref.c (get_references_in_stmt): Use value of second
        argument for build_aligned_type, and only the type to build
        a zero second argument for MEM_REF.
        * internal-fn.c (expand_mask_load_optab_fn,
        expand_mask_store_optab_fn): Likewise.
