Boris Brezillon 2611dc106a pan/bi: Disallow non-zero .{range,base} on load_push_constant instructions There seems to be several lowering pass that don't take the base/range into account, like nir_lower_mem_access_bit_sizes(). This caused issues when we tried using it on push_constants to make sure accesses are 32-bit aligned, so let's make sure the frontend is propagating the base to the offset, and assigns range to zero (AKA undefined).
