[PATCH] D21464: [PM] WIP: Introduce basic update capabilities to the new PM's CGSCC pass manager, including both plumbing and logic to handle function pass updates.

[Chandler Carruth via llvm-commits]

chandlerc added a comment.

Rebase and fix a fundamental bug in the callgraph update due to incorrectly
tracking edges demoted to references. Also clean up the patch itself to avoid
some weird diff churn that was present in the previous patch (sorry about
that).

Responses to questions and more comprehensive testing still coming...
