    c++: coroutines and range for [PR118491]

    The implementation of extended range-for temporaries in r15-3840 confused
    coroutines, because await_statement_walker and the like get confused by the
    EXPR_STMT into thinking that the whole for-loop is a single expression
    statement and try to process it accordingly.  Fixing this seems to be a
    simple matter of dropping the EXPR_STMT.

    gcc/cp/ChangeLog:

            * semantics.cc (finish_for_stmt): Don't wrap the result of
            pop_stmt_list in EXPR_STMT.

    gcc/testsuite/ChangeLog:

            * g++.dg/coroutines/coro-range-for1.C: New test.
