  * change of representation for GenCmm, GenCmmTop, CmmProc
  The type parameter to a C-- procedure now represents a control-flow
  graph, not a single instruction.  The newtype ListGraph preserves the 
  current representation while enabling other representations and a
  sensible way of prettyprinting.  Except for a few changes in the
  prettyprinter the new compiler binary should be bit-for-bit identical
  to the old.
