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.

Constant early on, because we can do it in doFinalization.

Tighten up a comment.

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().

Header files will be on the way.

Change the Opcode enum for PHI nodes from "Instruction::PHINode" to "Instruction::PHI" to be more consistent with the other instructions.

and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}

Moved enum and command-line option in separate file. Also added function that returns the user selected register allocator to the caller.

Check in my register allocator state-saving code.

Shorten the markSuggestedColorUsable method.
Add a switch for saving reg. alloc. state (coming soon).

but forgot to mention it.)

Remove more excess whitespace.

excess whitespace a little. Also improved some comments.

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().
