Implement the basic approach for instantiating types, with a lot of FIXME'd
stubs for those types we don't yet know how to instantiate (everything
that isn't a template parameter!).
We now instantiate default arguments for template type parameters when
needed. This will be our testbed while I fill out the remaining
type-instantiation logic.
