During subtyping/incorporation we transform types (e.g. changing nullability, form of the type) and, basically, we're doing this to some FIXPOINT. It's important that we use `KotlinType.hashCode()` to compare types, but for error types hashCode is a hashCode of its supertype and, for example, `makeNullableAsSpecified` method recreate type every time. So, we continue to generate new constraints and we'll never stop incorporation algorithm
