Quickly recognize when PBE conjectures are infeasible (#2718)
Recognizes when the conjecture has conflicting I/O pairs. Also includes a minor change to the default behavior of PBE.
This change broke a delicate regression array_search_2, which I fixed by adding some additional options to make it more robust.
After this PR, we immediately find 4/7 unsolved in PBE strings of sygusComp 2018 to be infeasible.
