This is perf-neutral on the major benchmarks.
Benchmark report for SunSpider, V8, and Kraken on bigmac (MacPro5,1).
VMs tested:
"TipOfTree" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/DumpRenderTree (r105082)
"OldJIT" at /Volumes/Data/pizlo/tertiary/OpenSource/WebKitBuild/Release/DumpRenderTree (r105082)
"GetterCache" at /Volumes/Data/pizlo/quartary/OpenSource/WebKitBuild/Release/DumpRenderTree (r105082)
Collected 12 samples per benchmark/VM, with 4 VM invocations per benchmark. Emitted a call to gc() between sample measurements. Used 1
benchmark iteration per VM invocation for warm-up. Used the portable Date.now() method to get millisecond-level timing. Reporting
benchmark execution times with 95% confidence intervals in milliseconds.
