/** Naive Side Effect Tester --

* If Naive Side Effect Tester is set to true, Lazy Code Motion
* uses the conservative side effect information provided by the
* NaiveSideEffectTester class, even if interprocedural information
* about side effects is available. The naive side effect analysis
* is based solely on the information available locally about a
* statement. It assumes, for example, that any method call has the
* potential to write and read all instance and static fields in
* the program. If Naive Side Effect Tester is set to false and
* Soot is in whole program mode, then Lazy Code Motion uses the
* side effect information provided by the PASideEffectTester
* class. PASideEffectTester uses a points-to analysis to determine
* which fields and statics may be written or read by a given
* statement. If whole program analysis is not performed, naive
* side effect information is used regardless of the setting of
* Naive Side Effect Tester.
