Rob Clark	5d3895d13b	nir: Add way to create passthrough TCS without VS nir ... In the case of disk-cache hits, radeonsi no longer has the nir shader around. So add a way to create a passthrough TCS with just the VS output locations.

Rob Clark	a8e84f50bc	nir: Add helper to create passthrough TCS shader ... Based on si_create_passthrough_tcs() as that seemed the most generic of the various different backend driver implementations. Uses the load_tess_level_outer_default and load_tess_level_inner_default intrinsics to load the gl_TessLevelOuter and gl_TessLevelInner values, so driver will somehow need to implement those to load the values set by pipe_context::set_tess_state() or similar.
