Owen Anderson 5c53a46297 Enable stack slot coloring DCE. Evan's spiller fixes were needed before this could happen.

Owen Anderson 81db491b7f Add a quick pass to the stack slot colorer to eliminate some trivially redundant spills after coloring.
Ideally these would never get created in the first place, but until we enhance the spiller to have a more
global picture of what's happening, this is necessary for code quality in some circumstances.

Dan Gohman 9bb56443a1 Teach StackSlotColoring to update MachineMemOperands when
changing the stack slots on an instruction, to keep them
consistent with the actual memory addresses.

Evan Cheng 71013f8c78 Remove option used to debug stack coloring bugs. It's no longer needed since stack coloring is now bug free.

Evan Cheng c72dcd103c Instead of adding an isSS field to LiveInterval to denote stack slot. Use top bit of 'reg' instead. If the top bit is set, than the LiveInterval represents a stack slot live interval.
