Revert 154747 "Throw exceptions on all failed cross-origin acces..."

> Throw exceptions on all failed cross-origin access checks.
> 
> Rather than special-casing access to Location properties[1], we should
> allow developers to safely swallow cross-origin access check failures by
> throwing an exception upon access to potentially interesting properties.
> 
> For example, Firefox currently throws exceptions for cross-origin access
> such as `window.parent.NaN` and `window.parent.history`. This patch
> matches that behavior by throwing on access to Window properties and the
> History object.
