jsc performance: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, and JSRegress on oldmac (MacPro4,1). VMs tested: "TipOfTree" at /Volumes/Data/pizlo/secondary/OpenSource/WebKitBuild/Release/jsc (r159740) "CopySymTab" at /Volumes/Data/fromMiniMe/secondary/OpenSource/WebKitBuild/Release/jsc (r159740) Collected 10 samples per benchmark/VM, with 10 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.

You surely don't want to share watchpoints over global code? So, global code doesn't have a SymbolTable in UnlinkedCodeBlock. That SymbolTable is part of JSGlobalObject! And I think I just don't want to do constant inference for eval variables. I don't believe that the machinery I have for constant inference would even work for those. Those get sort of added dynamically using a put_to_scope. So, global variable constant inference currently already just works even with caching since each new JSGlobalObject gets a fresh symbol table. I don't care about eval's. That leaves functions!
