        * resources/sunspider-analyze-results.js: Tweak the output format a little.
        Change so that when there's only one run we don't write out confidence
        intervals at all rather than writing "NaN" over and over again.

        * sunspider: Use the time and date as a suffix on the results file, that way
        all the results are left behind in the tmp directory. This will make it easy
        for us to add features that compare past results in the future. Also rename
        the .mshark files using the same scheme.

        * sunspider-compare-results: Relax the parsing rules so we can parse the
        results file exactly as it's emitted from sunspider.
