  Log Message:
  -----------
  [c++20] For P0732R2: Give class NTTPs the proper type when examined with 'decltype'.

This requires that we track enough information to determine the original
type of the parameter in a substituted non-type template parameter, to
distinguish the reference-to-class case from the class case.
