Original commit message:
    Up until now we sometimes pass Smi 0 around as closure and expect the
    runtime to translate that appropriately. But we need to be careful in
    some places to not confuse the Smi 0 with a real closure. However, we
    could instead just pass the correct closure extracted from the native
    context.

    This addresses three long-standing TODOs in the JSTypedLowering pass.
