[export Data.Map.toDescList, foldlWithKey, and foldrWithKey (trac ticket 2580)
qdunkan@gmail.com**20080922213200
 
 toDescList was previously implemented, but not exported.
 
 foldlWithKey was previously implemented, but not exported.  It can be used to
 implement toDescList.
 
 foldrWithKey is already exported as foldWithKey, but foldrWithKey is explicitly
 the mirror of foldlWithKey, and foldWithKey kept for compatibility.
