 Let's split this PR. I will shortly open a new PR to track the 3.4 issue, we
 keep this one only for the 3.3 reduced snippet. In other words, the bug we
 track here is:
 
 ---------------------------------------------
 template <class  P, class Q>
 struct pair {};
 
 template <typename T>
 struct pair<T, INVALID> {
     typedef T first_type;
 };
 
 ---------------------------------------------
 pr10722.cpp:5: error: type/value mismatch at argument 2 in template
 parameter list for `template<class P, class Q> struct pair'
 pr10722.cpp:5: error:   expected a type, got `INVALID'
 pr10722.cpp:6: internal compiler error: Segmentation fault
 Please submit a full bug report,
 
 This is an ice-on-illegal, 3.3 regression with respect to 2.95 where the
 code was not ICE-ing the compiler.
