Bug: https://github.com/dart-lang/sdk/issues/37896 dart2js disallows JS interop classes from extending Dart classes, and ddc does not work as expected. Dart classes that extends JS interop classes can't be declared in ddc and throw an error on usage in dart2js. This CL adds static errors for both cases.
