[PATCH] D78968: [llvm][utils] Update llc test updater documentation

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Added some users of `update_llc_test_checks.py`.

`link attributes` is not clear. Do you mean `dso_local` or `dso_preemptable`? The problem you described seems like a general stale test problem. Missing `dso_local` may be a problem but I don't know whether that is common. Maybe there are more common problems that are worth mentioning.
