From: Ian Romanick <ian.d.roman...@intel.com>
Once the i965 driver stops calling _mesa_ir_link_shader, this
information is no longer set.
Ideally gen6_upload_vs_push_constants should use the
gl_shader_program, but I don't see a way to propagate the information
there. The other alternative, since this is the only usage, is to
move gl_vertex_program::UsesClipDistance to brw_vertex_program.
This should also probably get squashed into the previous commit.
