        This patch updates the test harness to report new metrics of Speedometer 2.0.

        Replaced the total time by the geometric mean of the time spent in each suite, and added scores
        as a metric in addition to time. Also, updated the PerfTestRunner harness and the results template
        to support "Score" metric with "pt" as its unit.

        StyleBench: Attribute selectors and other improvements
        https://bugs.webkit.org/show_bug.cgi?id=182387

        Reviewed by Joseph Pecoraro.

        - Add some attributes to elements in all tests
        - Add some attribute selectors to stylesheets in all tests
        - Also add some * selectors to all stylesheets.
        - Add attribute mutation step to all suites
        - Make test steps do more mutations (25->100) and reduce the number of steps to keep testing time in check.
          Too fast steps were running into timer resolution limits.

        The test should be doing multiple rounds of mutations in a single document to test what is supposed to test (like it did before r227756).
        This also makes test results more stable and less dependent on possible first-time costs.

        Generate 10 rounds of class/element mutation steps.
        Give each generated step unique name so reporting works.
