URL: https://github.com/llvm/llvm-project/commit/a18181931f991b04caea297e723db415756f09a0 DIFF: https://github.com/llvm/llvm-project/commit/a18181931f991b04caea297e723db415756f09a0.diff LOG: [NFC][clang] Add a CHECK lines to tests checking offsetof-like expressions I am looking at constant-folding changes that could affect these tests, so check that it emits the expected global value instead of just checking that it doesn't crash.
