Revert "r600g: precompute some of the hw state"
This reverts commit
de0b76cab22caa9fc7260f80acb8f151ccced6c5, its pre-computes the texture state wrong,
you can't just use an array of levels, since you can have FBOs to depth texture slices inside a level as well
it would get really messy quickly. Probably need to split commits like this up into pieces for each piece
of state, so we can revert bits easier in case of regressions.
This also break 5 piglit tests, and valgrind starts to warn about invalid read/writes after this.
