  * reimplement Data.Graph.Inductive.Query.Dominators
  It was buggy and very slow for large graphs. See
    http://www.haskell.org/pipermail/haskell-cafe/2008-April/041739.html
  This patch also adds a new function, iDom, that returns the immediate
  dominators of the graph nodes.

    M ./Data/Graph/Inductive/Query/Dominators.hs -27 +107
