Keep comments of type abbreviations to tuples - #1317
Merged

Conversation
The compiler reports the members of the abbreviated type as members of the abbreviation itself, e.g. Item1 and Item2 for `type P = int * int`. Those members were registered in the cross-reference resolver and read as members of the abbreviation. With warn-on-missing-docs on, looking up such a member hit its declaring entity (System.Tuple, FSharpList, System.String), which is never registered, and the resolver threw "The entity ... was not registered before". The exception escaped the whole entity read, so the abbreviation's own comment was dropped. An abbreviation declares no members, so the symbol reader no longer lists the target type's members on its page, and the resolver no longer registers them. Resolving a member whose declaring entity is not in the documentation set now falls back to an external link instead of throwing. Fixes fsprojects#1314
