It does what it's supposed to do: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on dethklok (MacBookPro9,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r183602) "FoldIsBlah" at /Volumes/Data/pizlo/primary/OpenSource/WebKitBuild/Release/jsc (r183602) Collected 6 samples per benchmark/VM, with 6 VM invocations per benchmark. Emitted a call to gc() between sample measurements. Used 1 benchmark iteration per VM invocation for warm-up. Used the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark execution times with 95% confidence intervals in milliseconds.

Had to skip some tests in http://trac.webkit.org/changeset/183638 and http://trac.webkit.org/changeset/183643. webkit.org/b/144463 tracks the fix.
