Nikolaj Bjorner 10145366b2 #5425 
Add an alternative to unit-subsume-simplify
It is called solver-subsumption
It does a little more than unit-subsume-simplify and also uses a different decomposition algorithm for clauses.
It removes redundant constraints and simplifies clauses in a single pass.
A possible use of this tactic is in isolation where the maximal number of conflicts
(smt.conflicts_max, sat.conflicts_max) are bounded. For simpler formulas full solver calls may be still feasible.
