Summary [[SetPrototypeOf]] isn't properly implemented everywhere

Reported 2016-03-02 17:15:33 PST
We inline parts of OrdinarySetPrototypeOf in a few different places that call O.[[SetPrototypeOf]](v) rather than doing full dynamic dispatch. We should put those inlined bits inside OrdinarySetPrototypeOf and have the call sites not inline parts of OrdinarySetPrototypeOf. This is wrong because this behavior is observable with proxy.
