The csel-ladder we have in bi_lower_load_push_const_with_dyn_offset() is not great, and is relying on base/range being valid. It turns out nir_lower_mem_access_bit_sizes(), which we rely on to make push constant accesses 32-bit aligned, doesn't preserve those when splitting accesses. Let's simplify the thing by lowering push constant accesses with a dynamic offset to global loads. We also reset the base and offset values in the lowering pass, to make sure the backend doesn't rely on them for other things.
