[PATCH] D29865: [PDSE] Add a no-op pass.

[Davide Italiano via Phabricator via llvm-commits]

Also, it would be great if you can provide real examples of where this helps (e.g. how often do you expect this to trigger in practice, and why it matters).
I assume you experimented enough with this to have a complete'ish pass somewhere out-of-tree. If so, did you run this on something to measure the impact?
Side question: do you want this to be run as part of the default pipeline eventually? What's the compile time cost?
