Please, fix this ASAP. This issue might hide other performance regressions. check-llvm for > 1 hour should not be acceptable.

Finally, all pipeline passed successfully. However, from updated logs, this is not look like a CI issue, as such slowdown happened during tests execution:

Logs have strange line: Passed With Retry: 1, correct logs doesn't have such line, probably such test caused this slowdown. Unfortunately, no more information in the logs. Such slowdown looks flaky, it doesn't happen now on other pre-commits. Submitted #8563
