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!

f3d3ca18b5 Added MachineCodeForInstruction object as an argument to
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.

35880f394f Instead of checking op.getType() against MO_VirtualRegister and
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

1617e6c997 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.

f57b845547 * Rename MethodPass class to FunctionPass
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)

7b3640bd12 Optional args are no longer allocated as they are discovered.
(This can be improved to avoid making the initial pass over the method.)
Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.

6111a87b3a Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
