- Only adds 'new issue' if no other label is added
(https://github.com/llvm/llvm-project/issues/65701)
- No not add labels if labels were already set
- Only add `foo` if there are no `foo:bar` label being added (although,
we don't use that yet)
Fixes#65701
This patch:
* Replaces `andymckay/labeler` which does not appear to be maintained by
github official solution
* Removes the closed issue workflow which was disabled a few years ago
and never fixed.
* Adds a few rules to add label based on PR title, hopefully that can
make triaging simpler. If that turns out to be useful, we can consider
adding more rules for backends, etc. We could technically also pattern
match the body of the issue but I'm concerned about trying to be _too_
clever.
The new system is only triggered on PR open so manual labels should not
be removed.
LLVM forks may use GitHub Actions as well as the upstream projects,
but they do not necessarily follow the same development processes.
Disable automatic issue labeling for forks, so that it does not
interfere with downstream repo automation.
