1ddf684f4c Major bug fix though it happened rarely (only on a compare after an
integer overflow):
We need to use %icc and not %xcc for comparisons on 32-bit or smaller
integer values.

66969014b2 Added special register class containing (for now) %fsr.
Fixed spilling of %fcc[0-3] which are part of %fsr.
Moved some machine-independent reg-class code to class TargetRegInfo
from SparcReg{Class,}Info.

4c524344b9 - 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.

e61bc07952 Convert RegClass::IsColorUsedArr from a dynamically allocated array to
a vector.  This makes asserting on array bounds easier.

fa6c24db76 Numerous bug fixes:
-- correct sign extensions for integer casts and for shift-by-constant
   instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section
-- folding getelementptr operations with mixed array and struct indexes
-- use uint64_t instead of uint for constant offsets in mem operands
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

4c0bf66bdd * Minor cleanups
* Reduce number of #includes
* Remove blatently misleading qualifiers (how do you have an inlined pure virtual function?)
* Remove unnecesary & ignored qualifiers (const int argument vs int argument)
* SparcInternals.h now no longer #includes RegClass.h or SparcRegClassInfo.h
* Pull inlined functions out of .h file if they are virtual and interfere with dependencies

b581a10ba4 Reordered registers slightly to simplify a new check.
Added a function to map between the caller's and callee's register windows.
