    c++: access checking in aggregate initialization [PR96673]

    We were deferring access checks while parsing B<int>{}, didn't adjust t=
hat
    when we went to instantiate the default member initializer for B::c,
    deferred access checking for C::C, and then checked it after parsing
    B<int>{}, back in the main() context which has no access.  We need to do
the
    access checks in the class context of the DMI.

    I tried fixing this in push_to/pop_from_top_level, but that caused seve=
ral
    regressions.
