    Make __proto__ a foreign callback on Object.prototype. · ce1e10f5
    mstarzinger@chromium.org authored
    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.
