On AMDGPU SGPR spills are really spilled to another register. The spiller creates the spills to new frame index objects, which is used as a placeholder. This will eventually be replaced with a reference to a position in a VGPR to write to and the frame index deleted. It is most likely not a real stack location that can be shared with another stack object. This is a problem when StackSlotColoring decides it should combine a frame index used for a normal VGPR spill with a real stack location and a frame index used for an SGPR. Add an ID field so that StackSlotColoring has a way of knowing the different frame index types are incompatible. llvm-svn: 308673
