[Mesa-dev] [PATCHv2 11/14] i965/gen7: Enable fragment shader dispatch if the program has image uniforms.

[Francisco Jerez]

Shaders with image uniforms may have side effects.  Make sure that
fragment shader threads are dispatched if the shader has any image
uniforms.

v2: Use brw_stage_state::nr_image_params to find out if the shader has
    image uniforms instead of checking core mesa data structures (Ken).
