i965: Start using HIZ for Z16 textures.

I had left this out for a long time because it regressed some
depthstencil-render-miplevels cases when it was enabled.  Now that the
bugs causing those are fixed, there's nothing stopping us.

Improves glbenchmark 2.1 offscreen performance by 7.3% +/- 2.8% (n=10).
