[PATCH] D37089: [Sema] Error out early for tags defined inside an enumeration.

Thanks for following up, Alberto. I haven't expected such a use case. It is possible to achieve the same with `LSA_SIZEOF_SA = sizeof(((len_and_sockaddr *)0)->u)` but I don't like it and don't want to force developers using such approach.

For solving this problem I think to restrict error only to C++ and to allow tags inside enums for C. Alberto, what do you think, will it work for you? And from implementation perspective allowing tags in enums for C should be safe because things go haywire for C++ while checking access rules and C doesn't have access rules.
