d30efaf56e * 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

f57b845547 * 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

7b3640bd12 Optional args are no longer allocated as they are discovered. 
(This can be improved to avoid making the initial pass over the method.)
Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.
