This is intended to mirror the any type in the WASM GC spec.
Make the optimized form of variant actually i31 without assuming the representation during generics specialization. Then we do the `i * 2 + 1` conversion during LIR printing and wasm lowering. Eventually, the WASM one will be replaced by the actual WASM i31.
