For turnip, we use the "bindless" model on a6xx. Loads and stores with the bindless model require a bindless base, which is an immediate field in the instruction that selects between 5 different 64-bit "bindless base registers", a 32-bit descriptor index that's added to the base, and the usual 32-bit offset. The bindless base usually, but not always, corresponds to the Vulkan descriptor set. We can handle the case where the base is non-constant by using a bunch of if-statements, to make it a little easier in core NIR, and this seems to be what Qualcomm's driver does too. Therefore, the pointer format we need to use in NIR has a vec2 index, for the bindless base and descriptor index. Plumb this format through core NIR.
