[PATCH] D87045: [LoopNest] Handle loop-nest passes in LoopPassManager

[Alina Sbirlea via Phabricator via llvm-commits]

asbirlea added a comment.

The design looks good, but I'd like to see more comments documenting some of the details for future code readers.
e.g. document the Optional<PreservedAnalysis> as including the test for skipped passes in that single function call (this is new behavior vs other implementations), document the addPass specializations and populating IsLoopNestPass.
