        This patch adds a CLI version of JS2 to run on watchOS. We run most subtests
        from the browser version of JS2, but skip a few tests that are particularly
        long running, like WSL and some of WTB. We also don't run the Wasm tests
        as we don't JIT on watchOS. Each test runs for fewer iterations in the watch
        version. 15 is the default iteration count. This benchmark runs in 7 minutes on
        a Series 4 watch.

        Make JSC memory benchmark available on OpenSource
        https://bugs.webkit.org/show_bug.cgi?id=195012

        Reviewed by Saam Barati.

        This patch upstreams the RAMification memory benchmark to open source.

        The prior RAMification.py driver script in the Internal directory has been moved here
        with the device execution code seperated out to a new Internal driver script.
        As a result, command line argument parsing as well as acting on the resulting argument
        values has changed.  The remote device Runner creates an ArgumentParser object that is
        passed through main().  In main(), if we have an ArgumentParser, we use it otherwise we
        create one for benchmarking locally.  The arguments object returned from argument
        parsing is now passed to the Runner constructor so it can extract the settings appropriate
        for that particular runner.

        Added some sane argument default values for the JSC command patch and the JetStream2
        source directory.

        Updated the Lua tests to eliminate the testing harness and its overhead, matching what was
        done in the Internal tree.

        The idea of BigIntBench is to provide a set of microbenchmarks and
        benchmarks to evaluate how fast BigInt computations are happening on
        JSC implementation.

        Now, we are adding microbenchmarks in this set,
        but the plan is to move these tests to "JSTest/microbenchmarks" when
        BigInt is enabled by default. After that, the focus of Bigint bench is
        to provide a set of tests that represents real use cases of BigInt in
        JS programs.

        Make JetStream 2
        https://bugs.webkit.org/show_bug.cgi?id=187829

        Rubber-stamped by Mark Lam.

        This patch checks in the new JetStream 2 benchmark. JetStream 2 is
        a new JavaScript and Web Assembly benchmark. JetStream 2's goal
        is to measure the startup, worst case, and peak throughput performance
        of the JavaScript engine. JetStream 2 incorporates these previous
        benchmarks:
        - JetStream
        - ARES-6
        - Kraken
        - Web Tooling Benchmark
        - WasmBench
        - RexBench
        
        JetStream 2 also adds some new benchmarks:
        - Two tests emphasizing web worker performance.
        - One test emphasizing Promise, async iteration, and DataView performance.
        - Two new code load tests.
        - WSL: a test measuring all kinds of things, especially emphasizing exception performance.

        * JetStream2: Added.

        [MotionMark] Add support for version numbers
        https://bugs.webkit.org/show_bug.cgi?id=186479

        Reviewed by Said Abou-Hallawa.

        Add support for displaying the version number as well as including it in the JSON results.

        When loading the front page, script replaces any element with classname version with the
        version number of the benchmark, which is stored in Strings.version.

        The JSON structure for the results includes a new version property:
            {
              "version": "1.0",
              "options": { ... },
              "data": [ ... ]
            }

        When dragging a results file, the version listed will come from the JSON file. Older
        results will not have had the version property, in which case it will default to "1.0".

        * MotionMark/index.html: Update title to some other default. Script will update it.

        results out to JSON, and displaying the results panel in developer mode.

        in the results object.
        (ResultsDashboard.version):
        (window.benchmarkRunnerClient.willStartFirstIteration): When running the benchmark, pass the
        benchmark version string to the dashboard, which holds the results.
        (window.sectionsManager.setSectionVersion): Helper function to update the element in the

        (window.benchmarkController.showResults): When showing results, update the version string

        Allow the ramp controller to run tests that take less time than the initial ramp-up phase
        https://bugs.webkit.org/show_bug.cgi?id=186257

        Reviewed by Said Abou-Hallawa.

        * MotionMark/tests/resources/main.js: Extend the desired end timestamp when ramp-up occurs.
        Previously the controller assumed that the duration of the test was always longer than the
        time it took to figure out the order of magnitude of particles to render. When that range
        is determined, the end timestamp is then extended. If the duration is too short, the controller
        would throw an exception. The fix is to continue extending the timestamp every time the order of
        magnitude tiers up.

        In general testing with really short durations isn't practical, but sometimes it is
        desired for debugging.

        To avoid confusion of the private variables, I renamed Benchmark._startTimestamp to
        Benchmark._benchmarkStartTimestamp, to disambiguate from Controller._startTimestamp.
        Benchmark._startTimestamp is set once and never changed, after the initial 100ms warm-up.
        Controller._startTimestamp is initialized to 0 (which means "not initialized"), and then after
        the warm up is complete, set in Controller.start() to the same wall clock timestamp, and never
        changed afterwards.
