[PATCH] D87951: Enable opt-bisect for the new pass manager

[Josh Stone via Phabricator via llvm-commits]

cuviper added a comment.

Hmm, thanks for those pointers. To combine opt-bisect from the two pass managers, maybe there can be an explicit call to copy stateful instrumentation? I think it helps that they are not interleaved, so we could do `MPM.run()`, then somehow `SI.copy_to(CodeGenPasses)`, then `CodeGenPasses.run()`. I still need to read that thread too...

`LTOBackend` may also need to deal with this, but I don't know if flags like opt-bisect apply there.
