  - Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

 - Implement SCCP of globals into ConstantExprs hopefully opening new
   opportunities for more SCCP.

  - GCSE now uses new Value #'ing interface, instead of dealing with AA itself
  - GCSE worklist implementation much simpler, class cleaned up.

* Move isMaxValue, isMinValue, isAllOnesValue to Constants.h

llvm-svn: 3290

   * 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.

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