Egor Zhdan 82c076c9d3 [cxx-interop] C++ reference types are not AnyObjects ...

C++ foreign reference types have custom reference counting mechanisms, so they cannot conform to `AnyObject`.

Currently Swift's type system treats C++ FRTs as `AnyObject`s on non-Darwin platforms, which is incorrect. This change makes sure the behavior is consistent with Darwin platform, i.e. a cast of C++ FRT to `AnyObject` is rejected by the typechecker.
