The only case we may need fake override for private members is
a situation when class refers itself with different type arguments.
So in this commit we forbid such fake overrides when we can prove
that class does not refers itself here.
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
