           Summary: Named creators with [OverrideBuiltins] don't work
                    right as the spec is written now

           Version: unspecified

Consider an interface with a named creator and [OverrideBuiltins] (in fact, the
only interface with a named creator in the platform has that extended
attribute).

When a set happens for a currently-nonexistent, per current spec
[[GetOwnProperty]] will return undefined.  Then the ES impl will go up the
proto chain looking for a setter, and if found call it.

That doesn't seem correct; we actually want to call the named creator in this
case.

We should probably just override [[Put]] when we have a named creator.  And
maybe transition all this stuff to the ES6 MOP in the process...
