[patch/testsuite] gdb.c++/classes.exp: add another ptype pattern

Ah, I threw a nested class into my little test program.  Its name in the
stabs changed from 'PrivClass' (3.2.3) to 'Outer::PrivClass' (3.3).  So
it's not just enums, it's nice and regular.

No end to this rabbit hole ...

I am inclined to proceed on the assumption that all gcc 3.X will
be like gcc 3.3 (gcc HEAD certainly is).  Let gcc 3.2 and previous
versions suffer.  Let gcc 2.95.3 suffer, too, although that hurts a bit
more.

I'm neutral on the question of starting a thread in gcc@.

Daniel J, what would you like to do?
