Jonathan Greene 3b5036a1e1 Fix required time handling for unconstrained POs, infinity arithmetic, and absDup cosmetic 
- Tim_ManInitPoRequiredAll: only overwrite PO required times when ALL are
  unconstrained; preserve user-specified constraints
- Gia_ObjPropagateRequired: propagate infinity unchanged through LUTs
- Tim_ManGetCoRequired: guard against infinity minus delay arithmetic
- Gia_ManDelayTraceLut: handle infinite required times in slack computation;
  allow negative slack to report timing violations
- Tim_ManCreate: fix required-time loading to address actual POs via
  Tim_ManForEachPo instead of p->pCos[] (wrong for designs with boxes)
- Tim_ManGetArrTimes/Tim_ManGetReqTimes: fix loop-exit detection using
  boolean flag instead of comparing iterator index against PO/PI count
- Gia_ManPrintFlopClasses: use Gia_ManRegBoxNum instead of Gia_ManRegNum
