e1d4fb3c2c Fix bug: LICM/2003-02-27-PreheaderProblem.ll 
There may be a single outside predecessor and
still need a new loop-preheader if the predecessor has multiple
successors.

bfa0786c7e - Add new methods to LoopInfo: getLoopPreheader, addBasicBlockToLoop. 
These allow extra information to be easily gathered, and loopinfo to be
    updated.

91d4742562 - Cleaned up the interface to AnalysisUsage to take analysis class names 
instead of ::ID's.
 - Pass::getAnalysis<> now no longer takes an optional argument

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.

const BasicBlocks

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

8e9be000a7 * Pull BasicBlock::pred_* and BasicBlock::succ_* out of BasicBlock.h and into 
llvm/Support/CFG.h
* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
  InstrTypes.h anymore
