f1a0a10813 Fix errors in computing downgrowing offsets, and in 
computing size of extra outgoing args.

5b43af962b Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

e64574ce71 Major change to how defs are found when adding dependences (they 
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before.  It is now.

6d35326cd5 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.

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).

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.
