Add aliases to map 'imm, mem' form of x86 bts/btr/btc without a size suffix to their 32-bit forms.
This makes them consistent with 'bt' which already had this handling. gas has the same behavior. There have been discussions on the mailing list about determining size based on the immediate, but my goal here was just to remove the inconsistency.
