c54839573c Make MachineOperand's value named 'contents'. Make really, really sure 
it is always completely initialized and copied.
Also, fix up many comments and asserts.

8517e1f0be Fix a __LONG__ term annoyance of mine: symbolic registers weren't being printed 
by operator<< on MachineInstr's, and looking up what register "24" is all of the
time was greatly annoying.

to an unsigned char so that overall MachineInstr's size stays the
same.

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

4d7af65903 Change interface of MachineOperand as follows: 
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.

a2dd745613 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

5f2180c533 (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".
