Brian Gaeke e8f7c2f863 Add head-of-file comments and Doxygen comments. Tighten up a lot of whitespace.
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().

Alkis Evlogimenos de8ac749fe Add parent pointer to MachineInstr that points to owning
MachineBasicBlock. Also change opcode to a short and numImplicitRefs
to an unsigned char so that overall MachineInstr's size stays the
same.

Alkis Evlogimenos 327426411e Modify the two address instruction pass to remove the duplicate
operand of the instruction and thus simplify the register allocation.

Alkis Evlogimenos 3d100ef0ca When an instruction like: A += B had both A and B virtual registers
spilled, A was loaded from its stack location twice. This fixes the bug.

Alkis Evlogimenos aaba4639f8 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.

Chris Lattner cd4f4320b0 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!

Vikram S. Adve 7366fa1aa6 (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".
