[Mesa-dev] [PATCH 2/8] i965: Disable HiZ on Haswell for now.

[Kenneth Graunke]

Getting HiZ working means updating all the state packets for resolves
and clears.  It's not worth doing until we get the basics working.

This patch won't apply cleanly without Eric's patch that makes HiZ support
a driconf option rather than an environment variable.  I figure that will
get cleaned up and land first.
