[C++ PATCH] PR c++/69855

[Ville Voutilainen]

Tested on Linux-PPC64. Comments very much welcomed on the change
to g++.old-deja/g++.pt/crash3.C, I'm not at all sure what that test
is trying to do; it looks like it may have never cared about the names
of the local functions, but rather about the fact that the function
bodies of the member functions of the class template are not instantiated
just because the member functions return types that are specializations
of the class template.
