time was greatly annoying.

Move out of line member functions of MachineBasicBlock to
MachineBasicBlock.cpp.

Rename SetMachineOperandConst's formal parameters to match other methods here.
Mark some methods as being used only by the SPARC back-end.
Fix a missing-paren bug in OutputValue().

MachineBasicBlock. Also change opcode to a short and numImplicitRefs
to an unsigned char so that overall MachineInstr's size stays the
same.

operand of the instruction and thus simplify the register allocation.

spilled, A was loaded from its stack location twice. This fixes the bug.

    a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

     not clobber them!

    Fixed spilling of %fcc[0-3] which are part of %fsr.

(2) Moved some machine-independent reg-class code to class TargetRegInfo
    from SparcReg{Class,}Info.

(3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly()
    and related functions and flags.  Fixed several bugs where only
    "isDef" was being checked, not "isDefAndUse".
