Bug detailed description:
-------------------------
It fails on Ironlake with mesa master branch, works well on 10.1 branch.
Following piglit cases also fail with same bisect commit:
spec_ARB_depth_buffer_float_fbo-clear-formats
spec_EXT_packed_depth_stencil_fbo-clear-formats
Bisect shows: f128bcc7c293013f4b44e4b661638333de0077c2 is the first bad commit.

i965: Drop mt->levels[].width/height.
It often confused people because it was unclear on whether it was the
physical or logical, and people needed the other one as well. We can
recompute it trivially using the minify() macro, clarifying which value is
being used and making getting the other value obvious.
v2: Fix a pasteo in intel_blit.c's dst flip.
