    [heap] Introduce separate pass for reseting phantom handles on Scavenge · da5a8e3d
    Michael Lippautz authored
    Resetting phantom handles while keeping finalizers alive leads to the
    problem of eagerly resetting a handle although another finalizer keeps
    it (transitively) alive.
    
    This becomes a problem with internal pointers to Blink as without
    global handle a Blink GC is free to collect wrappables.
    
    This CL untangles finalizers handling from phantom handle resets by
    introducing a separate path for resetting.
