Reviewed by Antti Koivisto.

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.

* Skipped: Unskipped the test.
* Speedometer/resources/benchmark-report.js:
(window.benchmarkClient.willStartFirstIteration..createTest): Added the unit as an optional argument
to report the score in addition to time. Also report the geomean of time instead of the total time.
(window.benchmarkClient.willStartFirstIteration): Report the geomean of time.
(window.benchmarkClient.didRunSuites): Record the entire measuredValues instead of just tests.
(window.benchmarkClient.didFinishLastIteration): Report the scores.
