Port ceade6cf Original commit message: This adds a new %NewArray runtime entry, which constructs a new JSArray and does the subclassing correctly (to the same degree that %NewObject does currently), and also deals properly with the AllocationSite feedback mechanism. This runtime entry will be used by TurboFan and is also used as a fallback in the subclassing case in the stub currently.
