ba1c1f2fb6 Pull predecessor and successor iterators out of the CFG*.h files, and plop them into 
the BasicBlock class where they should be.  pred_begin/pred_end become methods on BasicBlock,
and the cfg namespace isn't used anymore.

06028541ab Move the sparc target to a new lib/Target directory

ff0c8a7511 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.


NOTE! The BBLiveVar.cpp file dependant on the Sparc backend, and is therefore not generic/portale to other backends.  This needs to be fixed.
