        * calls.c (initialize_argument_information): Tighten pass-through
        conditions for pass-by-reference.  Remove dead TARGET_EXPR code.
        Use build_fold_addr_expr.
        (emit_library_call_value_1): Use build_fold_addr_expr.  Remove code
        that assumes ADDR_EXPR allocates stack space.
        * fold-const.c (build_fold_addr_expr_with_type): Look through
        WITH_SIZE_EXPR.
