It's possible to avoid this 'if' - by assuming the data is always there. It's possible to initialize it in the ScriptController. The 'if' will consume few clocks every time...

Also, we could have V8 expose Isolate::GetCurrentIsolateData() to avoid one extra non-inlinable call. Of course, only if it actually saves part of the expected perf problem :-)
