  * Fix performance regression in quotRemInteger/divModInteger
  This fixes most of the performance regression in these functions
  between 6.8.3 and 6.10.1, it was due to a slight difference in the
  strictness between the old and new versions (see comments for
  details).  There's still a few percent loss in performance in the div
  test in nofib/spectral/integer that I haven't tracked down as yet.

    M ./GHC/Integer.lhs -2 +13
