rL329801: [AMDGPU][MC][GFX9] Added v_screen_partition_4se_b32
Summary

See bug 36845: https://bugs.llvm.org/show_bug.cgi?id=36845

Note that V_MOVRELS_B32 has the same encoding as V_SCREEN_PARTITION_4SE_B32 (but the former is not supported by GFX9).

This patch also corrects V_MOVREL* opcodes which have no SDWA/DPP variants.
