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