Bug 1644878 - Don't define Map/Set identical iterator methods in self-hosted JS. r=arai I think we were defining those methods in self-hosted JS, because that automatically gives us the property that they all have the same identity. This causes bad error messages. Instead redefine them in the finishInit ClassSpec hook. We still have the "wrong" methods in the 'methods' array so that JSXray tests continue to pass.
