c++: local class in nested generic lambda [PR109241]

In this testcase, the tree walk to look for bare parameter packs was
confused by finding a type with no TREE_BINFO.  But it should be fine that
it's unset; we already checked for unexpanded packs at parse time.

I also tried doing the partial instantiation of the local class, which is
probably the long-term direction we want to go, but for stage 4 let's go
with this safer change.
