Original Issue: https://codereview.chromium.org/29353003/

This addresses the leak that mstarzinger points out (https://codereview.chromium.org/26390003/) and includes the test.

Note that this adds a test that observing changes to the empty-string property remains possible.

92bd4d1f2d I found this working on 
https://codereview.chromium.org/19541010/

The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this).

Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy.

It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy.

Both issues are now fixed and properly tested.

ce1e10f5fc Make __proto__ a foreign callback on Object.prototype. 
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.

The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.

oldValue when the value of a property has actually changed (or been removed,

6b16d0bcae Make Object.observe on the global object functional 
The approach in this change is to handle the unwrapping/wrapping of the global object transparently with respect to the JS implementation of Object.observe. An alternate approach would be to add a runtime method like %IsJSGlobalProxy and %UnwrapJSGlobalProxy, but it seems ugly to give JS (even implementation JS) access to the unwrapped global.

2e76922c79 Object.observe: Use [[DefineOwnProperty]] to create properties of changeRecord. 
Note: The test here requires https://codereview.chromium.org/11364237/ to land in order to pass because Object.freeze calls Object.getOwnPropertyNames().

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.

Further optimization is possible, but can be left for later.
