[ES6] Implement WeakSet https://bugs.webkit.org/show_bug.cgi?id=142408 Reviewed by Darin Adler. Source/JavaScriptCore: This patch implements ES6 WeakSet. Current implementation simply leverages WeakMapData with undefined value. This WeakMapData should be optimized in the same manner as MapData/SetData in the subsequent patch[1]. And in this patch, we also fix WeakMap/WeakSet behavior to conform the ES6 spec. Except for adders (WeakMap.prototype.set/WeakSet.prototype.add), methods return false (or undefined for WeakMap.prototype.get) when a key is not Object instead of throwing a type error.
