Bug 125711

Some clarification: this is the reason why we don't support GetByIdFlush right now.

Created attachment 263631 [details] WIP This is probably the patch, I just want to run perf numbers before landing.

Created attachment 263637 [details] patch Now with a changelog. I think this patch is ready for review. I'll run and post performance numbers before landing the patch (if performance is good/neutral).

perf: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, and JSRegress on Saams-Mac-Pro (MacPro6,1). VMs tested: "og" at /Volumes/Data/WK/os-a/OpenSource/WebKitBuild/Release/jsc (r191365) "FTLGetPutByIdFlush" at /Volumes/Data/WK/os-b/OpenSource/WebKitBuild/Release/jsc (r191365) Collected 8 samples per benchmark/VM, with 8 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. og FTLGetPutByIdFlush SunSpider: 3d-cube 10.3725+-0.3872 10.1750+-0.1102 might be 1.0194x faster 3d-morph 10.1964+-0.0382 ?
