A DeclRefExpr that refers to a member function or a static data member

of the current instantiation is value-dependent. The C++ standard
fails to enumerate this case and, therefore, we missed it. Chandler
did all of the hard work of reducing the last remaining
Boost.PtrContainer failure (which had to do with static initialization
in the Serialization library) down to this simple little test.

While I'm at it, clean up the dependence rules for template arguments
that are declarations, and implement the dependence rules for template
argument packs.
