C++: fix dereferencing of nested type and 'auto'

Browse Source 
Fixed case:
template<class T>
struct List
{
  struct iterator
  {
    T *operator->() { return &t; }
    T &operator*() { return t; }
    T t;
  };
  iterator begin() { return iterator(); }
};

struct Foo { int bar; };

void func()
{
  List<Foo> list;
  auto a = list.begin();
  (*a).; // code completion doesn't work
  a->; // code completion does not work
}
