  Log Message:
  -----------
  [Sema] Don't treat a non-null template argument as if it were null.

The way this code checks whether a pointer is null is wrong for other
reasons; it doesn't actually check whether a null pointer constant is a
"constant" in the C++ standard sense.  But this fix at least makes sure
we don't treat a non-null pointer as if it were null.
