Truffle/Instrumentation: first large merge of instrumentation code into the TruffleVM framework
- introduce the Instrumenter class, held by the TruffleVM to support instrumentation services
- reimplement Probe-realated services (formerly statics in Probe.java) to be provided by the Instrumenter- add new Accessors
- change the TruffleVM startup sequence
- change the APIs of the Debugger and many other classes
