Do we really want that? Just to put things in perspective the original file size was 45963 lines and the reduced one is now 1293 lines so we are talking about 35 such files. What Hank has done in this PR is to test each instruction with random register, address, and immediate instead of all the combinations that he had before so we still have a decent coverage. The test generator tool continues to have the ability to generate the full combination optionally.
