bd63458778 Shuffle assumptions on every call 
Order of assumptions appears to make a huge difference on what lemmas
are discovered. Shuffling the assumptions ensures that the solver
is never stuck with any bad order.

In merge, parents of A instead of parents of B were traversed.
Among other things, it created stale marks that caused an

f6dcc6fc72 API to find pob in pob_manager 2018-06-27 22:49:35 -04:00
Arie Gurfinkel
5bc57238a6 Track whether pob is in pob_queue 
pob_queue is a priority queue. Changing a pob while it is in the queue might change
the priority. This is a source of subtle bugs. The flag is ment to help defend
against this issues in the future.

As a side-effect, a pob that is already in the queue will be silently not added
to it, and a new version of a pob might be created if a version being looked
for is already in the queue.
