  Clamp negative coverage counters to zero.
  
  Because there is no locking on counter updates, race conditions may
  cause counters to become negative. Clamp them to zero when exporting
  LCOV reports.
  
  Optionally remove blank lines from coverage
  
  Added -omit-blank-lines option to add Skip regions to the coverage map
  for lines of source code that are blank.
