        * dwarf2out.c (address_of_int_loc_descriptor): Don't emit
        DW_OP_piece after DW_OP_stack_value, adjust size calculations
        for it, when DW_OP_stack_value and DW_OP_implicit_value has
        the same size, prefer DW_OP_stack_value.
        (loc_descriptor, loc_list_for_address_of_addr_expr_of_indirect_ref,
        loc_list_from_tree): Don't emit DW_OP_piece after DW_OP_stack_value.
