Subject: Add initial instrumentation to and fix warnings in DIS stressmarks

Changes:
- Backpoint fix to randInt range
- Instrument benchmarks with time tracking
- assert inputs are correct length to fix compiler warnings

Problems:
- Timing on a per-loop basis is non representative of real-world
  workloads, as we clear the cache after every loop. These all need
  to be re-instrumented to record times for the whole benchmark,
  rather than per-loop.
