Chris Lattner 6d14f2a7ae New functionality for instcombine: 
* New ReplaceInstUsesWith function to factor out tons of common code
     This needs to be used more in the future still, but it's a good start
   * 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
     testcase.

Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.

Chris Lattner 3cd8c56cbb Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking

 * 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

Chris Lattner 33fca976ee * 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.
