8dadbe31dc Update verifySavedState()'s comment, so that it reflects its current 
status.  In doFinalization(), skip over external functions, just like
Anand's mapping info does.

29d56dd004 Include llvm/CodeGen/MachineCodeForInstruction.h. Use it to start 
implementing verifySavedState().

In saveState(), use the new AllocInfo::AllocStateTy enum, and increment
Insn each time through the loop.

04e6824a3f Publicize the type of FnAllocState. 
Prototype option to save state in a global instead of as a Constant in
 the Module. (Turned off, for now, with the on/off switch welded in the off
 position. You get the idea.)

6d9f7ff0df Move AllocInfo structure to a private AllocInfo.h header file. 
Make FnAllocState contain vectors of AllocInfo, instead of LLVM Constants.
Give doFinalization a method comment, and let it do the work of converting
 AllocInfos to LLVM Constants.

5952eddbfb Don't worry about converting each function's reg. alloc. state into One Big 
Constant early on, because we can do it in doFinalization.

Tighten up a comment.

08fc8bcce4 Doxygenify method comments. 
Try to improve method comments a little.
Get rid of some excess whitespace; put braces on previous line when possible.
Add stub for method to verify the work of saveState().

but forgot to mention it.)

6dc46fce5a Convert PhyRegAlloc into a proper pass. 
PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().
 Remove unused inline void constructLiveRanges().

3862c570bc For instructions in a delay slot of another instruction, 
we no longer need to find the live-before set of the delayed
branch since that set is now included the live-before/after
set of the instructions in each delay slot.  Just assert that instead.
