96c466b06a Add new optional getPassName() virtual function that a Pass can override
to make debugging output a lot nicer.

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

0bc0516078 Don't pad spills and temp. stack areas for alignment.
Freeze auto vars and spill areas when their sizes are used
for computing other offsets.

1d21f3eb1d * Add a useful file comment
* Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp
   -> Among other things, this eliminates the need for the minstrVec static
      global array.

2fbfdcffd3 Change references to the Method class to be references to the Function
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

  InstrTypes.h anymore

699683c585 * Minor cleanups
* Reduce number of #includes
* Remove blatently misleading qualifiers (how do you have an inlined pure virtual function?)
* Remove unnecesary & ignored qualifiers (const int argument vs int argument)
* SparcInternals.h now no longer #includes RegClass.h or SparcRegClassInfo.h
* Pull inlined functions out of .h file if they are virtual and interfere with dependencies

7327d7ee8b Move a ton of tables out of SparcInternals.h and move them to Sparc.cpp.
Eventually they will probably get moved again, but at least now they aren't
having to be compiled by 7 different .cpp files...

00521d79bf When allocating space on stack for writing a register,
use the size of the register, not the size of the Value type,
to get the right alignment.

0714e3bc44 Make the sparc.burg file be a little more flexible and rubust in the fact of
renumbering of instructions.  It is still horribly broken and grossly dependant on the number of instructions, but now it is a least a little better.

Oh yeah it also works now.

46cbff625e Chris seems fond of #include <vector>. Fix these. Also convert use list in
Value to a vector instead of a list.

f6e0e28135 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.
