25ba5ac7ce - Do not expose Critical Edge breaking mechanics outside the BCE pass, thus 
removing it from Transforms/Local.h and from Transforms/Utils/*

49588769e0 - Expose passinfo from BreakCriticalEdges pass so that it may be "Required" 
by other passes.  Make BCE pass be in anonymous namespace now.

a4184f9ab6 Fix: ConstantMerge/2002-09-23-CPR-Update.ll 
Basically, this bug boiled down to calling replaceUsesOfWith on a constant,
which changed it's shape in an illegal way.  This pass now goes through all
of the trouble neccesary to do the replacement on constants.

   * New InsertNewInstBefore to allow multi-instruction replacements
   * Change getMaxValue functions to isAllOnesValue function, which doesn't
     have to CREATE/lookup a new constant.  Also the name is accurate
   * Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne
     functions:  This should be moved to Constant* classes eventually
   * Implement xor X, ALLONES -> not X
   * Fold ALL setcc's of booleans away
   * Handle various SetCC's for integers against values at the end of their
     ranges, possibly off by one.  This implements the setcc-strength-reduce.ll

5d9be21256 * Cleanups of instcombine 
- Reenable gep (gep x) -> x
   - Make instcombine do dead instruction elimination where it's really
     easy.  Now visitors don't have to ensure they aren't not processing
     dead instructions.

12b9a2a7e6 Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

b9052f081a * Fix bug: test/Regression/Transforms/ADCE/2002-07-17-AssertionFailure.ll 
which was caused by us not running the "drop references of dead
  instructions" code when there were no basic blocks that were dead.

  We still don't want to do some of the stuff we do if there are dead
  basic blocks, but we DO want to drop references of dead instructions,
  so we factor the common code out to a new method.
