Nikolaj Bjorner 061e94d723 #5858 
COI model converter has to use constraints from the body and work in disjunctive mode. It needs a pre-condition that the body does not depend on other rules, in the case that it is used in a different pre-processing step for in-lining. The in-lined occurrence of the predicate has to correspond to the model construction version.
