[Mesa-dev] [PATCH 4/5] i965: Clean up VS push constant upload code since removal of old path.

[Eric Anholt]

We used to have clip planes optionally included in the push constants,
resulting in a variable amount of data uploaded, but no more.  This also
means less wasted space in the batch for our push constants.
