Truffle/Instrumentation: a new flavor of Instrument that lazily provides an AST fragment to be attached/adopted directly into a running AST, and to which execution event notifications will be routed. Important use cases so far include conditional breakpoints (with optimizeable conditions) and Ruby set_trace_func.
