a0a3946882 Make a new llvm/Target #include directory. 
Move files from lib/CodeGen/TargetMachine to lib/Target
Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h}
Prepare to split TargetMachine.h into several smaller files

161b4af2f6 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.  :)

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.
