* Add a stub to FunctionPass so that subclasses can declare that they do not
...
modify the CFG. It currently does nothing, but will in the future.
* Changes to make the public PassManager.h be MUCH smaller, and devoid of
implementation details. Now PassManager is just a Pimpl class that wraps
PassManagerT<Module>, but lib/VMCore/Pass.cpp is now the only class that
has to #include PassManagerT.h

to fill in

they modify (be conservative!)

modifies the underlying program)
