commit f898793b4545483adaf62c5efbc78cee518884e6

    coroutines: Partial reversion of r11-437-g5ef067eb14d4.
    
    co_returns are statements, not expressions; they do not need
    to be wrapped in an EXPR_STMT.
    
    gcc/cp/ChangeLog:
    
            * coroutines.cc (finish_co_return_stmt): Revert change to use
            finish_expr_stmt.
