Jun Wu 0c36fd8b5e tests: translate some .t tests to Python
Summary:
Those tests were converted using:

  echo *.t | xargs -P20 -n1 python -m testutil.dott.translate --black --verify

They run 5x faster (via run-tests.py), and 10x faster (via python directly).

run-tests.py on old .t files, 652 CPU seconds:

  % time ./run-tests.py `cat list-t.txt`  --noprogress
  .................................................................................................................................
  # Ran 129 tests, 0 skipped, 0 failed.
  ./run-tests.py `cat list-t.txt` --noprogress  505.30s user 146.37s system 1451% cpu 44.899 total

run-tests.py on new py tests, 135 CPU seconds:

  % time ./run-tests.py `cat list-py.txt` --noprogress
  .............................................................................................................................
  # Ran 125 tests, 0 skipped, 0 failed.
  ./run-tests.py `cat list-py.txt` --noprogress  55.73s user 78.80s system 744% cpu 18.061 total

vanilla python on new tests, 59 CPU seconds:

  % time (for i in `cat list-py.txt`; do python $i; done;)
  ( for i in `cat list-py.txt`; do; python $i; done; )  41.61s user 17.47s system 90% cpu 1:05.31 total

The new tests also have auto fix ability. `python test-foo-t.py --fix` will
autofix the code.
