    arg: Save exception state when releasing an array
    
    In this loop, if an early element failed to release, then releasing
    subsequent elements could call JSAPI functions with an exception already
    pending. JS::AutoSaveExceptionState should do what we want here:
    temporarily clear the exception, then put it back at the end of the
    scope unless another exception was thrown.
