DIS fixes used for (rejected) RTSS'20 submission

- All: Output times to stderr and nothing to stdout
- Field, Update, Pointer: change definition of a job to match other
  stressmark execution times more closely
- Matrix: move all allocations into main()
- Update: Use volatile to prevent computations from being optimized out
- Transitive: Use volatile to prevent computations from being optimized out
- Neighborhood: Use working version of drawLineSegment from original DIS
