subsetmaker: rework the antichain generation to be usable
Before this, antichain computation can run for 10s of hours without completion in
sight. We use a more direct approach in the computation to keep the computation
in complexity in check. With good result.
We can now have a full antichain computation on mozilla-try in about one
minute. Which is usable.
