Given that
1) because of code flags mismatch we are not able to fetch any CompareIC stub that was put into the cache (we put MONOMORPHIC stubs but query only UNINITIALIZED ones),
2) it was already broken for a couple of years,
3) we will not need to cache any stub once CompareIC becomes vector-based.
