Is there a policy to judge whether or not to backport a miscompilation bug fix?
Actually, it is unlikely to trigger this bug in real-world projects. But this fix is simple and safe to be backported.

I am fine with not backporting this if the reason is "it depends on https://github.com/llvm/llvm-project/pull/137131".
