    c++, coroutines: Account for overloaded promise return_value() [PR105301].

    Whether it was intended or not, it is possible to define a coroutine
promise
    with multiple return_value() methods [which need not even have the same
type].

    We were not accounting for this possibility in the check to see whether
both
    return_value and return_void are specifier (which is prohibited by the
    standard).  Fixed thus and provided an adjusted diagnostic for the case
that
    multiple return_value() methods are present.
