e7d8ee84e7 Add support for ImmutablePasses, which are not run, and cannot be 
invalidated.

b270065c97 Add a new BasicBlockPass::doInitialization/Finalization(Function &) pair of 
methods that may be useful for BasicBlockPasses.

205af87264 Make getAnalysisToUpdate<AnalysisType>() public so that transformation APIs 
can update analysis information.

3baff38916 - Pass now has AnalysisImpls class to implement getAnalysis() so that it is 
correct even when called back by another passes run method.

30a25af88c Make the getAnalyss<> members const. Using them does NOT modify the Pass object.

48cb6df26f - Make Pass::lookupPassInfo a public member 
- Fix Pass::getAnalysis<AnalysisType>() to use dynamic_cast instead of a
    static cast to handle the case where the cast from & two classes are not
    related via inheritance.

50900b8381 - Cleaned up the interface to AnalysisUsage to take analysis class names 
instead of ::ID's.
 - Pass::getAnalysis<> now no longer takes an optional argument

* Prevent copying and assignment

ec2780457d * Standardize how analysis results/passes as printed with the print() virtual 
methods
* Eliminate AnalysisID:  Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
  the analyses themselves.

bd5095f570 Add support for passes to announce that they only depend on the CFG of a 
function.  This is crude but effective

to make debugging output a lot nicer.

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

3c0dcb01d4 Checkin new pass framework. This one is more useful and automatically 
creates analysis results for passes that need them.   MethodPass's never
have to worry about being invoked on external methods.

out how to run a collection of passes optimially given their behaviors and
charactaristics.
