nir: Add intrinsics for tessellation shader system values.
nir_intrinsic_load_patch_vertices_in corresponds to gl_PatchVerticesIn, a special input in both the TCS and TES stages. nir_intrinsic_load_tess_coord corresponds to gl_TessCoord, a special tessellation evaluation shader input. nir_intrinsic_load_tess_level_outer/inner correspond to the gl_TessLevelOuter[] and gl_TessLevelInner[] evaluation shader inputs, which we treat as system values because they're stored specially. (These intrinsics are only for the TES - the TCS uses output variables.) Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Iago Toral Quiroga <[email protected]>
