whessev8 d2a8454d2f This change removes the %AddProperty native JavaScript function from V8.
All uses of %AddProperty are replaced by %SetProperty.  A few uses of
IgnoreAttributesAndSetLocalProperty are added, and the runtime version
of it adds a PropertyAttributes argument.  Only the JSObject class
in objects.cc now uses AddProperty, and it can become private.
