Prior to this patch, generating test checks in place put the ATTR definitions at the very top of the file, above the RUN lines and autogenerated note. All CHECK lines should below the RUN lines and autogenerated note.
This change ensures that the attribute definitions are emitted with the rest of the CHECK lines.
