Keep track of inherited analysis. For example, if a loop pass does not
...
preserve dominator info then it should update parent FPPassManager's
available analysis info to reflect this.

Add preparePassManager() hook. This allows each pass to check whether
...
current active pass manager is appropriate or not.
A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this hook
and use new LPPassManager for itself.

Current pass manager, not the parent pass manager, assumes the role of

last user when one of the managed pass uses info provided by parent pass
manager.
