- actually use the calculated costs for scheduling
- calculate the register use of nodes

don't create Inc/Dec in transform phase but delay that decision for the finish phase (of course we still create IncMem and DecMem nodes)

- Source and Destination address mode are now constructed during the normal
  transform phase and not as a separate phase
- Remove the old ImmOp stuff
- introduce 8, 16bit cmps, tests
- still some nodes miss SourceAM handling, but generally we should be as good/better than the old code, so I'm comitting now
