Unfortuantely we don't know if a particular load is a real 2d image (as would be a cube face or 2d array element), or a layer of a 3d image. Since we pass in the TIC reference, the instruction's type has to match what's in the TIC (experimentally). In order to properly support bindless images, this also can't be done by looking at the current bindings and generating appropriate code. As a result all plain 2d loads are converted into a pair of 2d/3d loads, with appropriate predicates to ensure only one of those actually executes, and the values are all merged in. This goes somewhat against the current flow, so for GM107 we do the OOB handling directly in the surface processing logic. Perhaps the other gens should do something similar, but that is left to another change. This fixes dEQP tests like image_load_store.3d.*_single_layer and GL-CTS tests like shader_image_load_store.non-layered_binding without breaking anything else.
