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.

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. :)

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.
