[Mesa-dev] [PATCH 1/7] i965: Use 4 bits to store nr_userclip in brw_clip.h.

[Paul Berry]

Since the i965 driver supports 8 clipping planes now, we need 4 bits
to store the number of user clipping planes, not 3.

In theory this isn't strictly necessary, since brw_clip.h is only used
on pre-GEN6, and pre-GEN6 only advertises support for 6 clipping
planes, but it seems wise to err on the safe side.
