Original Commit Message:

    Before Turbofan/Ignition it was possible to use external profilers to
    sample running V8/Node.js processes and generate reports/FlameGraphs
    from that. It's still possible to do so, but non-optimized JavaScript
    functions appear in the stack as InterpreterEntryTrampoline. This commit
    adds a runtime flag which makes interpreted frames visible on the
    process' native stack as distinguishable functions, making the sampled
    data gathered by external profilers such as Linux perf and DTrace more
    useful.
