        <pre>Consider:

template<typename T> void f() {
  struct S { void g(int n = T::error) noexcept(T::error); };
}
template void f<int>();

We should reject this, because instantiating a function is supposed to
instantiate everything within the function, even pieces of a local class.

(Incidentally, failing to do this can lead to the "decl not instantiated in
this scope" assertion.)</pre>
