Predicate storeStepImpl

Holds if data can flow from node1 to node2 via an assignment to f. Thus, node2 references an object with a field f that contains the value of node1.

The boolean certain is true if the destination address does not involve any pointer arithmetic, and false otherwise. This has to do with whether a store step can be used to clear a field (see clearsContent).
