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

d6c5e0f535 For phi elimination, now we are generating only one instruction 
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

34b17e8a37 1. Add a bottom-up pass on BURG trees that is used to fix constant operands. 
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.

3e2a85a0e3 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.
