Summary: When we have new attributes and we end the fixpoint iteration because the iteration limit is reached, we need to treat the new ones as if they changed in the last iteration, as they might have. This adds a test for which we should not derive anything regardless of the iteration limit, e.g., if we abort there should not be any attributes manifested in the IR.
