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.
