1a33e6eb74 Small space optimization: Make MachineOperands take 16 bytes instead of
20 on intel or 24 on sparc

756a55000b Remove a 'using' directives from a header file. Using directives cause
global changes, so aren't good for headers.

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)
* s/Method/Function/g in other random places as well

7b3640bd12 Optional args are no longer allocated as they are discovered.

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.

69db8da023 Checkin changes to:
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
3. Sparc.h is now just a factory method.  Eventually this file will dissapear,
   but probably not until we have more than one backend.  :)

0e6530ee1b This checkin represents some cleanup of the backend, implementing the following things:
1. The TargetMachine structure is free to decide the process a particular target uses to generate code.
2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory.  The Sparc.h file that is globally visible is just a stub.
3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort.
