This revision is now accepted and ready to land.

The patch does 3 things now:

- update_test_checks.py: add an alias `-u` for `--update-only`
- port `--update-only` to other `update_*_test_checks.py` scripts
- the script aborts if the test file was generated by another `update_*_test_checks.py` utility

The description should probably reflect the situation.
