Changes in directory llvm/include/llvm:
PassManagers.h updated: 1.5 -> 1.6
---
Log message:
- Undo previous check-in (i.e. Do not export TimingInfo class through
PassManagers.h).
- Add StopPassTimer() and StartPassTimer() to expose TimingInfo to
CallGraphPassManager
- Use these two APIs in CalLgraphPassManager to measure timings.
