Benchmark report for SunSpider, Octane, and Kraken on sakura-trick.

VMs tested:
"baseline" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/ic-dfg-tot/Release/bin/jsc
"patched" at /home/yusukesuzuki/dev/WebKit/WebKitBuild/ic-dfg-value-add/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.
