c64ef6740a * 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

536cf1b13f * Rename MethodPass class to FunctionPass 
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well
