(1) Added special register class containing (for now) %fsr.

Browse Source 
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".
