nv50,nvc0: set vertex id base to index_bias
Fixes the piglits which check that gl_VertexID includes the base vertex offset: arb_draw_indirect-vertexid elements gl-3.2-basevertex-vertexid Note that this leaves out the original G80, for which this will continue to fail. It could be fixed by passing a driver constbuf value in, but that's beyond the scope of this change. Signed-off-by: Ilia Mirkin <[email protected]> Cc: "10.3 10.4" <[email protected]>
