Benchmark report for SunSpider on oldmac (MacPro4,1).

VMs tested:
"TipOfTree" at /Volumes/Data/pizlo/quinary/OpenSource/WebKitBuild/Release/jsc (r112326)
"VariableStream" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/jsc (r112326)

Collected 100 samples per benchmark/VM, with 100 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.
