8557b226f3 Insert code to load constants used as Call or Return arguments. 
Also, note return value of a Call as an "implicitUse".

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

f0604b84c7 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.

4cecdd206e Several fixes: 
(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".

c5b4632c27 Bug fixes: 
(1) Ensure that delay slot instructions are not moved out of place (this
    was happening for some CALL instructions).  Basically, we need to
    move all delay slot instructions out of the graph and handle them
    along with the delayed control transfer instruction.
(2) Mark scheduled instructions correctly when instructions are scheduled
    in more than one cycle in a single step (due to delay slots).

f6e0e28135 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.

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.

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