Log message for revision 72034:
  Add a --list-tests option.  It is useful when you want to trim down the set of
  tests, and want to be sure those and only those tests you want will be run.
  (You could do the same with test.py -vv, but several iterations of that with
  different combination sof -t/-m/-s/--layer/--level options might take ages.)
