        * objc-act.c (objc_build_setter_call): New.
        (objc_maybe_build_modify_expr): Rewritten to build a compound
        statement.
        (objc_build_incr_expr_for_property_ref): Updated calls to
        objc_maybe_build_modify_expr to call objc_build_setter_call
        instead.  Use build_modify_expr () instead of build2 (MODIFY_EXPR,
        ...).  Use convert () instead of build1 (NOP_EXPR, ...).  Use
        TREE_NO_WARNING on the final compound statement to silence C++
        warnings.
