i965/vs: Move compute_clip_distance() out of emit_urb_writes().
Legacy user clipping (using gl_Position or gl_ClipVertex) is handled by
turning those into the modern gl_ClipDistance equivalents.
This is unnecessary in Core Profile: if user clipping is enabled, but
the shader doesn't write the corresponding gl_ClipDistance entry,
results are undefined. Hence, it is also unnecessary for geometry
shaders.
This patch moves the call up to run_vs(). This is equivalent for VS,
but removes the need to pass clip distances into emit_urb_writes().
