Simplify representation of inversion Skolems for bv cegqi (#1164)
* Simplify intermediate representation of inversion skolems for cegqi bit-vectors. Cache bv inversion status globally in QuantifierEngine. Generalize virtual term policy for marking eligible instantiation terms. Enable regression.
* Enable other regression
