Native setters (see AccessorInfo in accessors.h) didn't have the ability
to return a result value. As a consequence of this, for instance, Reflect.set
on the length property of arrays had the wrong behavior:
var y = [];
Object.defineProperty(y, 0, {value: 42, configurable: false})
Reflect.set(y, 'length', 0)
The Reflect.set call used to return true. Now it returns false as
required by the spec.

Both of them shipped in Chrome 49 without incident.
Also move relevant tests from harmony/ to es6/.
