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.
