Failing to generate type referenced by a whitelisted type's constructor

[fitzgen]

Input:

namespace mozilla {
template <typename> class a {};
namespace detail {
class GuardObjectNotifier;
struct b;
}
class c {
  typedef detail::b d;
};
}
namespace js {
class D {
  mozilla::a<mozilla::c> e;
};
}
struct f {
  js::D g;
};
namespace js {
struct ContextFriendFields : f {};
}
class JSAutoCompartment {
public:
  JSAutoCompartment(mozilla::detail::GuardObjectNotifier);
};

Output with --enable-cxx-namespaces --whitelist-type JSAutoCompartment -- --std=c++11:

Hmm, well, bindgen knows about the detail namespace, that's good. Do we trace constructors at all right now?

[fitzgen]

We trace all methods, and we don't distinguish constructors from methods except with a MethodKind, so I would think we should trace constructors.

This is not true, they are actually separated. Patch incoming.
