        This adds a new test suite that will cover all of the path-based canvas calls.
        The patch will be divided up to cover tests with similar techniques.

        The simplest version uses a SimpleCanvasStage.

        * Animometer/runner/resources/tests.js: Add tests for quadratic, bezier, arcTo,
        arc, and rect segments. Also include arcTo, arc, and rect fills.
        * Animometer/tests/resources/stage.js:
        (Stage.prototype.randomBool): Added for counterclockwise property for arc segments.
        (Stage.prototype.randomInt): Fix how values are rounded, used by randomBool. It should
        round instead of flooring everything.
        * Animometer/tests/simple/resources/simple-canvas.js: Added. Defines common classes
        used by all simple canvas tests. The page reads best bottom to top.
        (SimpleCanvasStage): Basic stage. Pass a canvasObject which will be used to create new
        objects as needed in tune().
        (SimpleCanvasStage.prototype.tune): Modeled on other tests. Adds and removed objects
        as specified by the provided |count|.
        (SimpleCanvasStage.prototype.animate): Iterate over all the objects and ask them to draw.
        There is no "animating" of the objects; they will just paint statically on the canvas.
        (SimpleCanvasAnimator): Basic animator clears the canvas prior to painting.
        (SimpleCanvasBenchmark): Hard-code the feedback loop parameters instead of including
        them in the query parameters to the test URLs.
        (SimpleCanvasBenchmark.prototype.createAnimator):
        * Animometer/tests/simple/simple-canvas-paths.html: Added.

        * Animometer/tests/simple/resources/simple-canvas-paths.js: Added. There is no "animating"
        of these objects--they just paint statically on the canvas.
        (CanvasQuadraticSegment): Paint a quadratic segment stroke.
        (CanvasBezierSegment): Paint a bezier segment stroke.
        (CanvasArcToSegment): Paint an arcTo stroke.
        (CanvasArcSegment): Paint an arc stroke.
        (CanvasRect): Paint a rect.
        (CanvasRectFill): Paint a filled rect.

        (CanvasPathBenchmark):
        (CanvasPathBenchmark.prototype.createStage): Look for the pathType and create the
        stage using the right paint object.
        (window.benchmarkClient.create):

        All of the tune functions do an initial step of flooring the
        # of painting objects to add or remove. Factor that out since
        the complexity of all of these tests is always expressed in terms
        of countable items.

        * Animometer/runner/animometer.html: Remove the explicitly listed
        suites. These will be generated from Suites instead.
        * Animometer/runner/resources/animometer.js:
        (populateSettings): Iterate through Suites, and create the
        label and checkbox. Attach the Suite object to the checkbox so
        when the benchmark is started, we get direct access. Initialize
        the checkmark based on its value in localStorage. Set this to
        run when DOMContentLoaded is dispatched.
        (startBenchmark): Grab all of the checkboxes, inspect their
        values, add it to enabledSuites if selected. Remember whether
        the suite was enabled in localStorage, so that it's easy to do
        repeated runs.
        * Animometer/runner/resources/tests.js:
        (Suite): Create a new Suite class. Refactor out prepare() and
        run(), since all of them have the same implementation. Populate

        Instead of measuring the FPS of the animation, this benchmark measures the
        test complexity when rendering at a set-point FPS which should be lower
        than 60 FPS. This benchmark tries to stay at the set-point FPS by using
        a closed loop control system PID function. The gain of the system is passed
        as a parameter when running the test. Measuring the FPS faithfully results
        very fluctuating values. A Kalman filter is used to give a better estimate
        for the current FPS.

        The animation of the tests is done manually. requestAnimationFrame() is
        called with a callback. Inside this callback, the test is animating by
        changing the positions of the elements inside the page. The test complexity
        may change also if the current FPS is not equal to the desired FPS.

        and the tests runner are included in separate patches.

        changing the test to reach a desired FPS. It keeps asking the test page

        Reviewed by Mark Lam.
        
        The current percentile is 95%.  When I looked at the sample lists in our GC, it was
        clear that the worst 5% samples completely amortize our GC pauses.  Our GC pauses can
        be quite bad.  Clearly, splay-latency is meant to test whether we have an incremental
        GC that ensures that you don't have bad worst-case pauses.  But 95% is too small,
        because it doesn't really capture those pauses.  Raising the percentile to above 99%
        appears to do the trick.  99.5% or more seems like a good bet.  The trade-off there is
        just that if we set it too high, then we won't have enough statistics.  Doing this very
        clearly rewards GCs that are incremental, and punishes GCs that aren't (like ours).
        That's what we want, since in the future we want to use this test to guide any
        improvements to the worst-case performance of our GC.

        The way that the percentile is selected will also affect mandreel-latency.  That's a
        good thing, because 95% is probably too low for that test as well.  That test ends up
        with >10k samples.  The goal of using 95% in the first place was to get enough samples
        to have a stable average.  But if we have >10k samples, we can push that percentile up
        much higher and still get good statistics while achieving the effect we want - i.e.
        getting the worst case.

        I don't think that we need to do the same thing for cdjs.  That test only takes 200
        samples, so 95% means we report the average of the worst 10 samples.  That's probably
        good enough.

        JetStream should include a JavaScript version of the CDx real-time benchmark
        https://bugs.webkit.org/show_bug.cgi?id=146156

        Reviewed by Geoffrey Garen.
        
        This adds a JavaScript port of the CDx real-time benchmark to JetStream, and retires
        the cordic test because it was previously the smallest and probably least interesting.
        
        The new test, "cdjs", is mostly a faithful rewrite of the Java code into JavaScript.
        I got the Java code from https://www.cs.purdue.edu/sss/projects/cdx/.
        
        There are some differences:
        
        - It uses RedBlackTree's for all sets and maps rather than hashtables. This is clearly
          more in the spirit of real-time than the CDx benchmark. FWIW, CDx used to use trees
          and I don't know why that changed in the latest version.
        
        - CDjs doesn't attempt to avoid memory allocations, unlike the real-time Java version.
          I wrote the code that I wanted to write for aesthetics, rather than the code that I
          would have written if I tried to write the fastest code possible. Again, I believe
          that this is in the spirit of CDj - it's meant to test what would happen if you wrote
          real-timey stuff in a high level language and actually took advantage of that
          language to be more productive.
        
        The test score reflects the average latency of the worst 10 samples out of 200 samples.
        The simulation uses 1000 aircraft, flying along paths that result in some detected
        collisions every once in a while. The benchmark validates its results by checking the
        total number of collisions detected.
        
        Apart from the integration into the JetStream harness, the CDjs directory contains a
        fully self-contained benchmark that could be run either in the jsc shell or in browser.
        
        This new code uses the same 3-clause BSD license as the Purdue code, and gives
        attribution to Purdue in almost all files. I believe that is appropriate since I wrote
        most of the JS files by looking at the Purdue Java code and trascribing to JavaScript.
        In some cases, I even copy-pasted the Java code, like the complicated math for
        four-dimensional intersections and voxel hashing.

        JetStream should have a more rational story for jitter-oriented latency tests
        https://bugs.webkit.org/show_bug.cgi?id=145762

        Reviewed by Geoffrey Garen.
        
        JetStream has some latency tests that are meant to measure jitter.  Prior to this change, they
        did this by computing the RMS.  But the RMS is a pretty bad metric.  The thing that it rewards
        isn't really the thing that you'd want your browser to do.  These RMS-based tests involve taking
        the geomean of the RMS of some samples and the sample average.  The lower the geomean, the better
        (in the JetStream harness we then invert the scores so that higher is better, but let's ignore
        that for this discussion and assume that lower is better).  Here's an example of how this can go
        bad.  A browser that always computes a task in some horribly long time (say, 1000ms) but never
        varies that time will perform better than a browser that usually computes the task super quickly
        (say, 10ms) and sometimes just a little bit less quickly (say, 15ms).  The former browser will
        have an RMS of 0 and an average of 1000.  The latter will have a RMS somewhere around 3.5 and an
        average of 12.5 (assuming equal probability of 10ms and 15ms).  The geomean of (0, 1000) is 0.
        The geomean of (3.5, 12.5) is 6.6.  Lower is better, so the former browser scores higher - even
        though it's obviously never better to have a browser always complete a task in 1000ms when a
        different browser can do it in 15ms in the worst case.

        JetStream should not have this pathology.  The right way of avoiding it is to replace RMS with
        some other metric of how bad things get.  A good metric is the average of the worst percentile.
        The worst 1% or the worst 5% would be good things to average.  This will catch cases where the VM
        jittered due to JIT or GC, but it never have the pathology that we end up giving the better score
        to a VM whose best case is worst than another VM's worst case.
        
        For now, this change uses the highest samples above the 95% percentile. I'm not yet sure if that
        is the best thing - it might include too many scores that are around the best-case performance -
        but it's certainly better than RMS and it might be good enough to keep. But because of that
        uncertainty, I'm setting the version to be "1.1-alpha1" to indicate that we aren't ready to
        release this yet.

        Reviewed by Gavin Barraclough.

        Right now, run-perf-tests runs BYEBench 4 times with different instances of DRT/WTR to get
        a more stable time and account for differences in the runtime environment, particularly,
        ASLR (Address Space Layout Randomization).

        While we can't account for the latter effect when the benchmark is ran inside a browser,
        we can at least run 20 iterations to get a more stable (but perhaps biased by ALSR) number.

        While the sample size of 20 is statistically unsound to compute the arithmetic mean from,
        it's MUCH better than the current sample size of 5.

        LongSpider 3d-morph result check is inappropriate.
        <https://webkit.org/b/130928>

        Reviewed by Filip Pizlo.

        The LongSpider 3d-morph component expected result check is incorrect.
        The existing test checks if the leading digit of a sum starts with "-1".
        However, it turned out that the expected sum is in the order of
        -1.8735013540549517e-16 (i.e. very close to 0).  With small errors in
        the terms of the sum adding up, it is very easy for the resultant sum 
        to fluctuate.  There is no guarantee that the resultant sum's most
        significant digit will start with -1 either.

        The fix is to do a tolerance check on all the terms of the sum as well
        as the total sum value instead.  The tolerance should be more lenient
        for the sum which accumulates error from the individual terms, then for
        individual terms.

        Reviewed by Andreas Kling.

        Added Full.html that runs 5 iterations of DoYouEvenBench. This is the canonical DoYouEvenBench,
        which is also runnable by run-perf-tests.

        * DoYouEvenBench/Full.html: Added.

        * DoYouEvenBench/benchmark.html:
        (startTest): Updated the code to account for the fact old measuredValues is pushed down to tests
        property and we now have total property so that we don't have to manually compute the total.

        * DoYouEvenBench/resources/benchmark-report.js: Added. When we're inside a DRT/WTR, use
