5e7b796479 Object.observe: Move notification of JSArray length changes to JSArray::SetElementsLength 
The previous implementation in Accessors::ArraySetLength failed when array length was set through StoreIC_ArrayLength. But that stub and the accessor both delegate to JSArray::SetElementsLength, so moving the code there allows notifications to be sent in both cases.

92db2105e4 Object.deliverChangeRecords should remove the observer from activeObservers 
To preserve ordering guarantees during end-of-turn delivery, Object.deliverChangeRecords needs to remove the delivered-to observer from the list of active observers.

The added test demonstrates this behavior.

Wins back ~1500 points on Octane/Gameboy that we lost with
https://codereview.chromium.org/11365111 (CL 12900), presumably
by lowering register pressure and/or handlification overhead.
Hopefully benefits other regressions as well.

GetScriptOrigin is used for DevTools instrumentation.

If inspected call-site is inside "eval" then returned script name is "undefined". To fix this problem we can use the "nameOrSourceURL" method of script-wrapper.
