regression fix to ackerman gc and memory smash, perf fix for handling bv2int axioms, perf fix for filtering ackerman

Browse source 
this update addresses some perf regressions introduced when handling axioms for bv2int and a memory smash regression when decoupling bv-ackerman from in-processing. It adds a filter based on bv_eq_axioms for disabling ackerman reductions on disequalities.
