    libstdc++: Fix constraints on std::optional converting assignments
[PR117858]

    It looks like I copied these constraints from operator=(U&&) and didn't
    correct them to account for the parameter being optional<U> not U.

    libstdc++-v3/ChangeLog:

            PR libstdc++/117858
            * include/std/optional (operator=(const optional<U>&)): Fix copy
            and paste error in constraints.
            (operator=(optional<U>&&)): Likewise.
            * testsuite/20_util/optional/assignment/117858.cc: New test.
