    c++: array DMI and member fn [PR109666]

    Here it turns out I also needed to adjust cfun when stepping out of the
    member function to instantiate the DMI.  But instead of adding that tweak,
    let's unify with instantiate_body and just push_to_top_level instead of
    trying to do the minimum subset of it.  There was no measurable change in
    compile time on stdc++.h.

    This should also resolve 109506 without yet another tweak.
