Vikram S. Adve cecde7122c Big bug fix: getUsableUniRegAtMI needed to return values in arguments 
but did not pass the arguments by reference!
Also added a function to get a register class by ID.

Chris Lattner b1def732af * Eliminate the LiveVarSet class, making applyTranferFuncForMInst a static 
function in the one .cpp file that uses it.  Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
  templates that will eventually be moved to Support.

Chris Lattner 669a74ce8a Make #include "llvm/Analysis/LoopDepth.h" be an internal artifact of how register allocation is implemented.

Chris Lattner b0da8b2de1 * Minor cleanups 
* Reduce number of #includes, sometimes drastically (LiveRangeInfo.h lost _7_)
* Move instrIsFeasible() from InstrScheduling.h to SchedPriorities.h
* Delete blank lines at end of files

Chris Lattner 0a823a062c 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.
