Truffle/Instrumentation: second merge of instrumentation code into the TruffleVM framework
- deprecate Node.isInstrumentable() and Node.createWrapperNode(), now Instrumenter methods
- Instrumenter uses new Accessor methods to delegate implementation to TruffleLanguage implementations
- rework many instrumentation-related tests
