[Mesa-dev] [PATCH 3/3] gallivm/tgsi: fix issues with sample opcodes

This is actually really a RFC.
Another solution would be to also encode the target (either with or
without shadow information) in the instruction too though it seems a bit
unnatural for these instructions.
Or to not encode them as Texture instructions (so as before) but then
some other method is needed to handle offsets.
(In any case the gallivm code was wrong in using the
Inst->Texture.Texture field before since these weren't texture opcodes.)
