The spec omits the receiver arg with the idea arrow functions with lexical |this| will obviate the need for it.

de7352db92 Temporarily disable optimization for StringWrappers to use native valueOf 
V8 stores this information directly in the map of the wrapper, however,
it is not invalidated when the prototype of the wrapper is changed, so
once the bit is set, it is no longer possible to override valueOf.

This bug is currently hidden in Chrome since the i18n extension always
modifies the String.prototype, and so the optimization never kicks in.
Disabling the optimization temporarily allows for snapshotting i18n now.
