[PATCH] D143634: [ModuleUtils] Assert correct linkage and visibility of structors' COMDAT key

[Marco Elver via Phabricator via cfe-commits]

melver added a comment.

This is currently more an RFC - there might be other side-effects not yet accounted for, so please review carefully.

Although I have been able to reproduce the issue with an LTO and ASan build quite easily. If this is a common usecase for us, we might potentially save a good amount of .text size because of the 1000s of redundant structors.
