    Fix Work Balance computation in RTS stats
    
    An additional stat is tracked per gc: par_balanced_copied This is the
    the number of bytes copied by each gc thread under the balanced lmit,
    which is simply (copied_bytes / num_gc_threads).  The stat is added to
    all the appropriate GC structures, so is visible in the eventlog and in
    GHC.Stats.
    
    A note is added explaining how work balance is computed.
    
    Remove some end of line whitespace
    
    Test Plan:
    ./validate
    experiment with the program attached to the ticket
    examine code changes carefully
