Value:

namespace llvm { \
  template<typename T> typename Registry<T>::node *Registry<T>::Head = nullptr;\
  template<typename T> typename Registry<T>::node *Registry<T>::Tail = nullptr;\
  template<typename T> \
  void Registry<T>::add_node(typename Registry<T>::node *N) { \
    if (Tail) \
      Tail->Next = N; \
    else \
      Head = N; \
    Tail = N; \
  } \
  template<typename T> typename Registry<T>::iterator Registry<T>::begin() { \
    return iterator(Head); \
  } \
  template REGISTRY_CLASS::node *Registry<REGISTRY_CLASS::type>::Head; \
  template REGISTRY_CLASS::node *Registry<REGISTRY_CLASS::type>::Tail; \
  template \
  void Registry<REGISTRY_CLASS::type>::add_node(REGISTRY_CLASS::node*); \
  template REGISTRY_CLASS::iterator Registry<REGISTRY_CLASS::type>::begin(); \
  }

Instantiate a registry class.

This provides template definitions of add_node, begin, and the Head and Tail pointers, then explicitly instantiates them. We could explicitly specialize them, instead of the two-step process of define then instantiate, but strictly speaking that's not allowed by the C++ standard (we would need to have explicit specialization declarations in all translation units where the specialization is used) so we don't.
