Assert that we do not call isKnownFinal on methods marked final.
Assert that we do not call isKnownFinal on methods marked final.

We only use this within the devirtualizer, and we should never see
devirtualizable calls to explicitly final methods (since we don't create
these during SILGen). This is just future proofing in case that changes.
