    c++, coroutines: Improve check for throwing final await [PR104051].

    We check that the final_suspend () method returns a sane type (i.e. a c=
lass
    or structure) but, unfortunately, that check has to be later than the o=
ne
    for a throwing case.  If the use returns some nonsensical type from the
    method, we need to handle that in the checking for noexcept.
