FrameState and Graphviz changes: * removed popx, pushx methods from GraphBuilder * FrameState subclass of Value * added String shortName() to Node * added GraphvizPrinter option to use short names * small hack in GraphvizPrinter: omit FrameState->Local connections * added GraalGraphviz to implicit classpatch (read from GRAAL env var)
