The current HEAD of compiler-builtin's master branch no longer passes CI tests. Error reports failing at testcrate/tests/cmp.rs:34:9 for powerpc64le-unknown-linux-gnu target.

Bisection shows that the test still builds in nightly-2021-08-21 but fails in nightly-2021-08-22, so I suspect the issue is from LLVM upgrade #87570.

Initially discovered in rust-lang/compiler-builtins#405.
