b68af0c1e5 working on reconciling perf for arithmetic solvers 
this update integrates inferences to smt.arith.solver=6 related to grobner basis computation and handling of div/mod axioms to reconcile performance with smt.arith.solver=2.

The default of smt.arth.nl.grobner_subs_fixed is changed to 1 to make comparison with solver=2 more direct.

The selection of cluster equalities for solver=6 was reconciled with how it is done for solver=2.
