The `isInCycle` predicate would take a long time on Wireshark with 6GB RAM, sometimes OOMing in the fastTC HOP. Analyzing wireshark with 6GB is important because that's the standard configuration on our Jenkins workers. With this commit, I can analyze Wireshark with 6GB on my laptop. The `getNonPhiOperandDef` predicate on Wireshark is 34M tuples, while `getDefIfHasNeighbors` is 11M tuples, and the TC of `getDefIfHasNeighbors` is 23M tuples (487 MB).
