[PATCH] D100917: [NewPM] Only invalidate modified functions' analyses in CGSCC passes

[Yuanfang Chen via Phabricator via llvm-commits]

ychen added a comment.

I think we should be careful about letting passes invalidate analyses directly. IIUC the only interface for propagating invalidation from passes is PreservedAnalyses. Is there any way to enhance PreservedAnalyses to achieve the same effect?
