i915: Enable texture tiling by default.

This now passes piglit testcases, and shows performance improvements
on openarena.  Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.

This regresses gen-teximage on my 855, and no piglit tests on my 945.
