- 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.

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.
