sadly, there aren’t any tutorials currently. The PassManager itself is rather well documented, so I recommend taking a look at that.
It also makes sense to take a look at a some of the simpler analyses and passes in-tree. I’d recommend DCE and DominanceFrontiers as starting points, as those are both quite simple and an easy read.
We’re certainly interested in any progress and experiences you make with this. If you’re willing, tutorials are very welcome!
Here’s Part 2 of Chandler’s talk. It’s this talk which gives a lot of detail regarding the new PassManager, as of October 2014: http://llvm.org/devmtg/2014-10/#talk11
