ec2b9a7850 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.

This was exposed by LPPassManager work.

1c3633e461 - 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.

e3068403bd At the beginning of run, initialize analyis info availability for _ALL_ 
pass managers. Otherwise, stale available analysis info, from the managers not
yet run, may cause pass manager to take wrong turn.

This fixes CBE test failures reported by nightly tester.

s/ModulePassManager/MPPassManager/g
s/FunctionPassManagerImpl_New/FunctionPassManagerImpl/g
s/PassManagerImpl_New/PassManagerImpl/g

Introduce FPPassManager to manage function passes and
BBPassManagers.

Now FunctionPassManagerImpl is an implementation class
used by externally visible FunctionPassManager to manage
FPPassManagers.

Module pass manager (MPPassManager) now manages FPPassManagers
and ModulePasses.
