a1d14f3555 Machine-independent code generation routines used in instruction 
selection.  These used to live in several different places before.

ef9c23f281 * Both Method & GlobalVariable now subclass GlobalValue 
* ConstPoolPointerReference now represents a pointer to a GlobalValue
* Methods name references are now explicit pointers to methods
* Rename Value::GlobalVal to Value::GlobalVariableVal to avoid confusion

69db8da023 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.  :)

0e6530ee1b 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.
