As Dan suggested offline, I created these helper methods. Once V8 supports
Private names, we can just replace the implementation of these methods.

(BTW, the fact that these methods don't take Isolate* implies that they are not
performance-sensitive:-)

     v8::Local<v8::Value> getHiddenValueFromMainWorldWrapper(v8::Isolate*, ScriptWrappable*, v8::Handle<v8::String> key);
 
     v8::Isolate* mainThreadIsolate();
     v8::Isolate* toIsolate(ExecutionContext*);
     v8::Isolate* toIsolate(Frame*);
 
     // Can only be called by blink::initialize
     void setMainThreadIsolate(v8::Isolate*);
 
     // Converts a DOM object to a v8 value.
