    [runtime] Introduce a proper %NewArray runtime entry. · ceade6cf
    bmeurer authored
    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.
