Thanks, @arsenm . We discussed internally and now removing the ```asanrtl bitcode is not found``` diagnostic. 

Hi @arsenm, @yxsamliu, @b-sumner , should I edit the lit test(https://github.com/llvm/llvm-project/blob/bb518655127ad49e527bbc2a57a5fd8a3f9f0495/clang/test/Driver/hip-sanitize-options.hip#L63) with generic diagnostic or remove it also?
