[PATCH] D101264: [IR] Optimize mayBeDerefined for known linkages. NFC

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Is this functionally changing behavior? (looks like it is, because the 'false' return could currently be overriden by the SemanticInterposable module metadata, resulting in a 'true' return even for these linkages?) If it is a functional change it should have test coverage at least.

(though I think it's unfortunate that this would make the noipa work more involved & add more slices of behavior that could be incorrectly used)
