Ilia Mirkin 5ba380c226 nvc0: enable FBFETCH with a special slot for color buffer 0 ...

We don't need to support all the color buffers for advanced blend, just
cb0. For Fermi, we use the special binding slots so that we don't
overlap with user textures, while Kepler+ gets a dedicated position for
the fb handle in the driver constbuf.

This logic is only triggered when a FBFETCH is actually present so it
should be a no-op most of the time.
