- 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.
