NumFuzz passes various flags to V8 testing randomly, which can lead to various flag contradictions with existing flags. Up to now the system ignored the check for contradictions and kept running the test cases, leading to false positives. This change adds a new v8 flag --exit-on-contradictory-flags that exists gracefully when a contradiction is detected. On the numfuzz side we now filter simple contradictions beforehand. Measurements showed that ~2% of all numfuzz tests ran into contradictions. Around half of them are simple contradictions (repetitions and inversions), which are now filtered beforehand. The remaining ones (redundant or contradictory implications) are now ignored.
