Changes in directory llvm/include/llvm:
Pass.h updated: 1.80 -> 1.81
PassManagers.h updated: 1.12 -> 1.13
---
Log message:
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.
