    Refactor WorkWrap, get rid of worthSplittingArgDmd
    
    Instead of first checking whether splitting is useful, and then firing
    up the worker-wrapper-machinery, which will do the same checks again, we
    now simply generate a worker and wrapper, and while doing so keep track
    of whether what we did was in any way useful.
    
    So now there is only one place left where we decide whether we want to
    do w/w, and that place has access to more information, in particular the
    actual types at hand.
