i965/gen7: Set up all samplers even if samplers are sparsely used.
In GLSL, sampler indices are allocated contiguously from 0. But in the
case of ARB_fragment_program (and possibly fixed function), an app that
uses texture 0 and 2 will use sampler indices 0 and 2, so we were only
allocating space for samplers 0 and 1 and setting up sampler 0. We
would read garbage for sampler 2, resulting in flickering textures and
an angry simulator.
Fixes bad rendering in 0 A.D. and ETQW. This was fixed for pre-gen7 by
