9afb283500 Move PMTopLevelManager, PMDataManager and FPPassManger classes into 
new PassManagers.h header.

This opens door for implementing CGPassManager in IPA library.

da5ae651e9 Start using PMStack. Now each pass is responsibe for assinging 
a pass manager for itself.

There is some opportunity to remove some dead code from PassManager.cpp.

e0b89a869d Add PMStack, a Pass Manager stack. 
Eventually, Top level pass managers  will use this to keep track of
active pass managers. Eass pass will also learn how to find appropriate
manager from these managers stack.

b4701a315f 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.
