The script harness was calling GetSigOpCount, HasValidOps, IsPayToAnchor, IsPayToScriptHash, IsPayToWitnessScriptHash, and IsPushOnly on the fuzzed CScript. All of these are already covered by the script_ops harness, which is the dedicated harness for CScript member methods. Also add the missing IsPayToAnchor call to script_ops so the move preserves coverage.
