This failed to solve the problem it was aimed at, and introduced just as many issues as it resolved. Realistically, we need to deal with the possibility that multiple modules might define different internal linkage symbols with the same name, and this isn't a problem unless two such symbols are simultaneously visible. The case where two modules define equivalent internal linkage symbols is handled by r252063: if lookup finds multiple sufficiently-similar entities from different modules, we just pick one of them as an extension (but we keep them separate). llvm-svn: 252957
