These tests were guarded with 'UNSUPPORTED: target={{.*}}-darwin{{.*}}', but
that check may unintentionally pass if LLVM is configured with a host triple
that specifies a specific Darwin flavor, e.g. macOS with
-DLLVM_HOST_TRIPLE:STRING=aarch64-apple-macosx13.0. All darwin flavors should
set 'system-darwin', so this is a safer feature to check.
