changes to the dependencies and stamp system:
* dependencies can only be of type ValueNode
* exactType is a boolean flag, not a separate RiResolvedType
* use different Stamp subclasses for IntegerStamp, FloatStamp, ObjectStamp and GenericStamp
* use different stamp for nodes that can be a target for dependencies
* use different PhiNode constructors for value- and non-value-Phis
* use correct stamps for ExceptionObjectNode and CurrentThread
