This narrowing is needed. The original `CHECK-NOT: 888` can match the mangled name of the source-file-name string, `_QQclX<hash>`, whose hash depends on the test's path. From one of my checkouts it fails at both `-O0` and `-O1`. The change is unrelated to this PR, though, so it might be cleaner as its own NFC PR.
