Continue refactoring to make `LoopData` first-class. Here I'm making the `LoopData` hierarchy explicit, instead of bouncing back and forth with `WorkingData`. This simplifies the logic and better matches the `LoopInfo` design. (Eventually, `LoopInfo` should be restructured so that it supports this pass, and `LoopData` can be removed.) <rdar://problem/14292693> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207180 91177308-0d34-0410-b5e6-96231b3b80d8
