    coroutines: No cleanups on goto statements.
    
    Minor cleanup, this is statement not an expression, we do not
    need to use finish_expr_stmt here.

    gcc/cp/ChangeLog:
    
            * coroutines.cc (await_statement_walker): Use build_stmt and
            add_stmt instead of build1 and finish_expr_stmt.
