0ee0c26f4e Fix bug: test/Regression/Transforms/InstCombine/2002-05-14-TouchDeletedInst.ll 
"This testcase caused instcombine to fail because it got the same instruction on
it's worklist more than once (which is ok), but then deleted the instruction.
Since the inst stayed on the worklist, as soon as it came back up to be
processed, bad things happened, and opt asserted."

to make debugging output a lot nicer.

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

a392a80a60 Significantly rework InstructionCombining to work better and to be cleaner. 
We now use an InstVisitor to delegate to different cases that we are
interested in handling.  We also fix the FIXME's by adding users to the
worklist when appropriate.

are being converted over to Function.

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
