NIR does not have these instructions. TGSI and Mesa IR both implement them using < and >=, repsectively. Removing them deletes a bunch of code and means I don't have to add code to the SPIR-V generator for them. v2: Rebase on 2+ years of change... and fix a major bug added in the rebase. text data bss dec hex filename 8255291 268856 294072 8818219 868e2b 32-bit i965_dri.so before 8254235 268856 294072 8817163 868a0b 32-bit i965_dri.so after 7815339 345592 420592 8581523 82f193 64-bit i965_dri.so before 7813995 345560 420592 8580147 82ec33 64-bit i965_dri.so after Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>
