[PATCH] D142473: [UTC] Add --version argument

[Nicolai Hähnle via Phabricator via llvm-commits]

nhaehnle added a comment.

A couple of thoughts, not really having a fully-formed opinion on this yet:

- This is a nice trick to avoid the problem of test churn.
- I worry about the complexity of maintaining the different versions.
- In the past, I have on occasion made commits that only re-run UTC on existing tests, without making any other changes, and without posting them for review.
  - I added `update_any_test_checks.py` in part to make that sort of change easier (though the primary motivation was to just update tests after code changes)
  - I wonder if / to what extent normalizing and perhaps automating this process is an alternative solution.
