For a future patch, is it important to keep the lowered SGPR spills to be recognized as spill instructions during regalloc. Directly lowering them into V_WRITELANE/V_READLANE won't allow us to attach the SPILL flag to their instructions. This patch introduces the pseudo instructions with the SGPRSpill flag set in their Desc. They will get lowered to equivalent instructions later during post RA pseudo expansion.
