changes towards a canonical representation of comparisons:
* new createNullCheckGuard helper method on CiLoweringTool
* replaced NullCheckNode with IsNullNode
* GuardNode and FixedGuardNode can be negated
* keep a list of conditions that are true/false in CheckCastEliminationPhase
* FixedGuardNode has only one condition
* GraphBuilderPhase creates canonical CompareNodes
* BooleanNodes can negate their usages
* added junit test for canonicalized compares
* removed junit test for negated instanceof
* added more thorough graph comparison for junit tests
* CheckCastEliminationPhase keeps track of conditions that are known to be true/false
