Don't always declare frag shader INPUT[0] as fragment position.
We were doing this for the sake of softpipe and the tgsi intergrepter since we always need the fragment position and W-coordinate information in order to compute fragment interpolants. But that's not appropriate for hardware drivers. The tgsi interpreter now get x,y,w information from a separate tgsi_exec_vector variable setup by softpipe. The new pipe_shader_state->input_map[] defines how vert shader outputs map to frag shader inputs. It may go away though, since one can also examine the semantic label on frag shader input[0] to figure things out.
