Class represents an indexed "ideal" register class, where non-general classes only allow defs that choose that class in the def_size callback. nir_opt_preamble will try to assign specialized classes where possible, falling back to the general class once the special-purpose classes are exhausted. AGX will use this mechanism to promote bindless texture handles to bound texture registers where possible, falling back to pushing the handle as a uniform where not possible. Supporting multiple classes in nir_opt_preamble allows this multi-level hoisting to work in a single nir_opt_preamble call with proper global behaviour. Add this concept to nir_opt_preamble so we can use it in AGX later in this MR.
