        DoYouEvenBench: Make it work on Internet Explorer 11 Release Preview
        https://bugs.webkit.org/show_bug.cgi?id=122406

        Reviewed by Darin Adler.

        On Internet Explorer 11, $(elem).closest('li').data('id') fails to find the containig li of elem once
        the first item is marked complete or deleted until we get back to the event loop in the jQuery/TodoMVC.
        Worked around this limitation by overriding app.getTodo to use each item's id computed in advance.

        Also use $.text instead of execCommand('InsertText') in FlightJS/MailClient since Internet Explorer
        doesn't support execCommand('InsertText'). Also select the recipient to avoid exceptions.

        https://bugs.webkit.org/show_bug.cgi?id=116811

        Reviewed by Sam Weinig.

        The goal of this benchmark is to have an overview of querySelector as typically used
        by webpages.

        It uses queries similar to what is used by popular websites and applies somewhat
        similar weighting for each type of query.

        The tree used for the queries is intentionally kept simple to ensure we measure QuerySelector
        a not purely the overhead of traversal.

        Add simple performance tests for regions, without nested named flows: a region chain and a flow article.
        The regions.js script is used to generate the tests and can set the following parameters: the number of regions,
        the number of paragraphs, the regions width, height, max-height and the propability of a forced break after a paragraph.

        The tests are skipped for now. They should be enabled once the regions performance is stable enough to create a baseline.

        Also stop measuring memory usage in Dromaeo tests because some Dromaeo tests (e.g. jslib-modify-jquery)

        Prior to this patch, there were terminology confusions between "runs" and "iterations".
        The term "run" should refer to running a performance test once, and "iteration" should
        refer to one measurement in the test. i.e. Executing run-perf-should once will result in
        a single "run" of performance tests and each test may execute multiple "iterations"
        to complete the run.

        Unfortunately, we still overload the meaning of "runs" in "runs/s" (is "function calls/s")

        to be caused by not garbage collecting between tests!

        This patch adds a new file, force-gc.html, and loads this file between

        The new test tries to stress detaching on a heavy subtree (2 levels deep but with 1,000 nodes per level).
        We set display: none on the root and measure the time it takes to update the tree. Note that we will also

        Reviewed by Ojan Vafai.

        This patch moves "private" methods and properties of PerfTestRunner into a closure so that they're
        inaccssible from outside. Also catch exceptions from test.run, test.done, and other runner code
        to ensure we call notifyDone() even if we broke tests. Otherwise DRT will timeout and we end up
        waiting for 10 minutes per each broken test on bots.

        Reviewed by Ojan Vafai.

        Add a simple linear regression analysis on results page to detect time-dependent distributions.
        We add a warning sign (inline SVG) when the regression gave us a slope of at least 0.01 and a R^2 of at least 0.6.
        Also added time-series graphs per run under the bar graphs so that humans can manually inspect them.

        A nice follow up would be to add some normality test (e.g. Shapiro-Wilk) to detect bi-modal distributions
        but we probably need to restructure the code to run it asynchronously since normality tests are slow.

        Web Inspector: serialize edge counts instead of indexes in heap snapshot
        https://bugs.webkit.org/show_bug.cgi?id=88324

        The serialized node structure currently holds an index
        of its first containment edge in the edges array.
        The index can be quite big (up to 7 digits for large snapshots).
        The patch changes the serialization format to pass
        node containment edge count instead. For most nodes the count
        is just a single digit number.
        This reduces serialized snapshot size and therefore its transfer time.

        The reason why we want to add a benchmark for document.getElementById()
        in spite of the fact that Dromaeo/dom-query.html is already testing
        document.getElementById(), is that Dromaeo/dom-query.html outputs one
        result for several benchmarks (i.e. getElementById().nodeType,
        getElementsByTagName()[0].nodeType etc), and thus we cannot observe

        Use runPerSecond instead of run to measure results in function calls per second (run/s) instead of time (ms).
        This allows us to continue measuring performance reliably even when WebKit's performance improves and results
        become too small for Date.now()'s precision (around 15 ms).

        It should also reduce perf. bots cycle time for slower tests because we limit the number of function calls by time.

        Reviewed by Ojan Vafai.

        Add PerfTestRunner.runPerSecond. It uses _runLoop but replaces _runner by _perSecondRunner
        to compute runs/s of runFunction.

        When _perSecondRunner is called for the first time, i.e. _completedRuns is 0 (notice this is -1
        in regular run/_runner), it slowly increases the number of function calls to runFunction between
        time measurements in order to discount the time used by new Date() calls themselves until the
        total time spent reaches 100 milliseconds.

        By default, runPerSecond runs the test for at least 750 milliseconds in each run, and executes
        21 runs, yielding the total run time of roughly 18 seconds. This is significantly faster than
        most of existing performance tests. Also see http://ejohn.org/blog/accuracy-of-javascript-time/.

        This patch halves the execution time of Bindings/dom-attributes.html

        Update our copy of the HTML5 spec used for performance testing to match the latest version
        https://bugs.webkit.org/show_bug.cgi?id=69364

        Unreviewed.  The patch is too large to post, so landing this unreviewed. :(

        The copy of the html5 spec we were using for testing was over a year old
        and didn't have any of the subresources with it (we were only using it
        as an HTML parsing benchmark).  I'm about to use it for testing
        the full load/render time of the benchmark, so I've updated to the latest
        version of the spec (now 8mb instead of 5mb) and inlined two of the
        CSS files.  (Inlining the CSS was necessary to make my testing consistent
        as there seems to be a race with some timer fired after CSS load.)

        Increasing from 5mb to 8mb showed a similar 30% slowdown in our parser
        benchmarks as expected.

        Add a microbenchmark for a full-page render of the HTML5 spec

        Reviewed by Adam Barth.

        This was designed to be a test for https://bugs.webkit.org/show_bug.cgi?id=68944
        But it seems that by far our dominating cost for the HTML5 benchmark is
        time spent laying out lines (which isn't actually that surprising).

        I'm adding the performance test for posterity.

        PerformanceTests/Parser/html-parser is only testing parsing of the head element
        https://bugs.webkit.org/show_bug.cgi?id=69283

        Reviewed by Adam Barth.

        While investigating https://bugs.webkit.org/show_bug.cgi?id=68944
        I found that the html-parser benchmark was only parsing up to the
        first script tag per loop!  We've fixed this by adding the sandbox
        tag which will deny all external loads and allow the parser to
        synchronously continue parsing the entire document to completion
        (as we had expected it was doing).

        This changes the profile somewhat.  Line number counting is much
        hotter, since we're actually accounting for the parse of the entire
        document in our sample.

        Total sample time only about doubles, from 1800ms to 3800ms on my machine
        which is less than I would have expected.
