fe09fb22aa Numerous changes in interface to class SparcRegInfo corresponding to
changes in class MachineRegInfo (see MachineRegInfo.h for details).

Added {LD,ST}[X]FSR instructions.

6418eac2f1 Have to save a boolean (setCC) value whenever use is outside the current
basic block.

Mark setCCInstr used as dest. of conditional-move as both a def and a use.

BA instruction no longer has the unused CC argument.

76ee6f70ea Significant changes to correctly spill CC registers and to correctly
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
   Also, cpMem<->Reg functions now return a vector of machine instructions.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
   needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
   since regs used to save values *across* an instruction are not obvious
   either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
   This is needed for conditional move operations.
   So an operand may need spill code both before and after the instruction.

Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
   so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
   handling CC registers since cpMem<->Reg handle those correctly now.

c9a0ca5171 MachineInstr* in vector are not const (and never really were)

Renamed "earliestForNode" to "earliestReadyTimeForNode".

7a4be9580e Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}.

Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.
