Came up while looking at the history.state stuff, the JSC generator generates code for [CachedAttribute] SerializedScriptValue attributes.

Rough patch as a possible solution, it probably needs more work to handle more [InitializedByConstructor] attributes (and i'm not sure hijacking that extended-attribute is even a good idea), and i haven't looked into the setters case.

I tried going with ForceSet() instead of using hidden attributes but i didn't find a way to reset the cached value in that case (would probably need to set the accessor function again, but it's internal to the v8 generated file), and a way to invalidate the value is needed for the history.state thing.

Ideas/comments welcome.
