    Original change's description:
    > [heap] Introduce LocalIsolate for main thread
    >
    > Add a LocalIsolate for the main thread to Isolate. This LocalIsolate is
    > kept alive during the whole lifetime of the Isolate. The main thread
    > LocalIsolate starts in the Running state in contrast to the background
    > thread LocalIsolates (those start in Parked).
    >
    > Code paths in Turbofan that used to create a LocalIsolate on the main
    > thread can now simply use the main thread LocalIsolate.
    >
    > LocalIsolate for the main thread will help in reducing differences
    > between the main and background threads. The goal is that the main
    > thread behaves more like a background thread.
    >
    > The main thread LocalIsolate should also make it simpler to share code
    > between main thread and background threads by using LocalIsolate for
    > both.
