Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, and AsmBench on hanayamata.

VMs tested:
"Baseline" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/nan12-master/Release/bin/jsc
"Patched" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/nan12/Release/bin/jsc

Collected 50 samples per benchmark/VM, with 50 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.
