        Reviewed by Maciej.

        * sunspider: Added a "--base" option that records the current test as a baseline.
        Moved the code to find the newest .mshark file into a function (since I needed to use
        it in the other script and I prefer to copy/paste a function).

        * sunspider-compare-results: Added logic to compare the baseline with the last
        run when you don't pass any parameters.

        * Scripts/run-sunspider: Pass the "--base" option through.

        * Scripts/sunspider-compare-results: Don't check the number of parameters; let
        the real script do that. Default configuration to Release to match run-sunspider
        so we don't end up building Debug just to compare results.
