This PR fixes the option
-H:+PrintPointsToStatistics. On top of that, it ensures that allTypeStateinstances are properly registered viaPointsToStats.registerTypeState(which is is nop ifPrintPointsToStatisticsis disabled).PointsToStats.registerTypeStatewas refactored out of the constructors ofSingleandMultiTypeState, because when the constructors are invoked from a subclass (e.g. when creatingConstantTypeState),registerTypeStatewould receive a only a partially initialized object. I've instead movedregisterTypeStateinto the places where instances ofTypeStateare created. Fortunately, most such places can be redirected via the factory methods inAnalysisPolicy, so the diff is quite small.
