f1ab4b4eac Change the ExitBlocks list from being explicitly contained in the Loop 
structure to being dynamically computed on demand.  This makes updating
loop information MUCH easier.

329c1c6c94 Improve encapsulation in the Loop and LoopInfo classes by eliminating the 
getSubLoops/getTopLevelLoops methods, replacing them with iterator-based
accessors.

2b7bb7a986 - Add new methods to LoopInfo: getLoopPreheader, addBasicBlockToLoop. 
These allow extra information to be easily gathered, and loopinfo to be
    updated.

97f51a3024 * 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.

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
