testcase

The attachment is valid C++ but clang seems to be tripped up by the typedef, as
though the typedef were triggering the instantiation before the definition.

$ clang++ -fsyntax-only b2953197.cc
b2953197.cc:13:16: error: no matching constructor for initialization of
      'Foo<int>::Baz' (aka 'Bar<int>')
 Foo<int>::Baz x;
               ^
b2953197.cc:3:30: note: candidate constructor (the implicit copy constructor)
      not viable: requires 1 argument, but 0 were provided
 template<typename T2> class Bar;
                             ^
1 error generated.
