[changing assignee as this is clearly a mesa bug]

piglit arb_shader_texture_lod-texgrad shows the problem (using
texture2DGradARB). 
Currently running it may also get you a fortify crash due to TXD having 4
inputs (the max in the context structure is 3).

I'm attaching a patch that has an implementation. Unfortunately I can't seem to
get it to work entirely correctly. The piglit test looks almost correct but has
several artifacts in random places. If someone could point me in the right
direction (as I'm completely clueless), I would be happy to finish it. In case
it matters, piglit does not show any new failures from this patch.
