one Value with another one in all operands and implicit references
of the machine instruction.

9568568b75 - Clean up interface to Sparc register handling a bit:
- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead
     of std::string's.
   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

8b170945ea 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.
