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.

llvm-svn: 8698

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

(I also zapped printMachineCode() and printLabel() at the previous checkin,
but forgot to mention it.)

Remove more excess whitespace.

llvm-svn: 8644

Fix typos in file header comment.

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().
