ed466a713a Added class MachineOptInfo as interface to target-specific
routines supporting machine code optimization.
Also added method MachineInstrInfo::getNOPOpCode().

58678cc06e Move all the code that creates code generation passes from Sparc.cpp to
TargetMachine.cpp, since it is entirely machine-independent.
Also, add options to disable optional back-end passes (preselection and
instr. scheduling).

to make debugging output a lot nicer.

536cf1b13f * 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

1004ba9d5f Don't pad spills and temp. stack areas for alignment.

for computing other offsets.

dbc90d1c0c * Add a useful file comment
* Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp
   -> Among other things, this eliminates the need for the minstrVec static
      global array.

bc15ae64dd 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  The Method class is obsolete (renamed) and all references to it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.

8e9be000a7 * Pull BasicBlock::pred_* and BasicBlock::succ_* out of BasicBlock.h and into
llvm/Support/CFG.h
* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
  InstrTypes.h anymore

8bfb48c8d3 Convert RegisterAllocator interface to opaque pass type, so that users do not
need to know _anything_ about RegAlloc to use it.  Well in the end maybe.

4c0bf66bdd * 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

78017556fc 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...
