[PATCH] D59918: [Attributor] Pass infrastructure and fixpoint framework

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

@fhahn, I could split the `Attributor` and the part that identifies the `AbstractAttributes` in the IR. 
This way the `Attributor` becomes more lightweight, there is less coupling, and its easier to reuse the framework for other `AbstractAttributes`.
