Try to fix https://github.com/llvm/llvm-project/issues/86790 `getFETokenInfo` requires `DeclarationName` shouldn't be empty and this will produce crash when checking name conflict of an anonymous `NamedDecl` in `Sema::PushOnScopeChains` and whether it's a reserved identifier or not. These wouldn't happen when it's a anonymous enum and we can skip the checking and just add the declaration to current scope. Co-authored-by: huqizhi <836744285@qq.com>
