mesa: Get rid of texture-dependent image unit derived state.
The point is to avoid having to re-validate all image units when
_NEW_TEXTURE is flagged, which can be expensive if the driver exposes
a large number of image units. This has been reported to fix a 36%
performance regression in the Synmark2 Multithread benchmark on the
i965 driver which exposes 192 image units.
