Truffle: Improved support for "probing" AST nodes:
- Node.isSafelyReplacaeableBy(Node) checks in advance if Node.replace(Node) would be unsafe (crash the VM).
- Hoist Probe() from language imlementations into Node; now completely language agnostic.
- Language implementations support probing by implementing Node.isInstrumentable() and Node.createWrapperNode()
- Node.Probe() throws ProbeException (without side effects) if the probe fails.
-- ProbeException contains an instance of ProbeFailure that diagnoses the failure in detail
- Additional measures to prevent instrumentation from being applied to internal InstrumentationNodes.
- Promote ProbeListener to top level interface and add a default implementation
