C++: fix instantiation of template special. with pointer argument

Fixed code completion for instantiation of template specialization
with argument as pointer, e.g.:
template <typename T>
struct Template
{ T variable; };
template <typename T>
struct Template<T *>
{ T *pointer; };
Template<int*> templ;
templ.pointer;
