<pre>ES6SampleBench should have a harness
https://bugs.webkit.org/show_bug.cgi?id=159246
Reviewed by Saam Barati.
This adds a simple web harness for ES6SampleBench. It runs Air and Basic 10 times for 200
iterations each and reports three metrics:
First iteration: the time it takes for the first iteration to run. This is the first
iteration after the benchmark is loaded into the iframe, so it's representative of what
would happen if one of these workloads only ran for a short time.
Worst 2%: of the last 199 iterations, the average of the worst 2% iterations. If code like
any of these workloads was used in an important event handler, you'd want that code to run
well in the worst case in addition to having great throughput.
Steady state: the total of the last 199 iterations. This is representative of what would
happen if you ran code like this for a long time.
The total score is the geomean of the firstIteration/worstCase/steadyState numbers of the
two benchmarks.
The harness does statistics using Student's T-distribution confidence intervals.
