The template specialization of std::hash for std::experimental::observer_ptr<T> allows users to obtain hashes of objects of type std::experimental::observer_ptr<T>.
For a given std::experimental::observer_ptr<T> p, this specialization ensures that std::hash<std::experimental::observer_ptr<T>>()(p) == std::hash<T*>()(p.get()).
