Asumu Takikawa
Because the Wasm GC proposal has three separate reference hierarchies (extern, any, func) since https://github.com/WebAssembly/gc/issues/307 was resolved, and they each need a distinct bottom type.
JSC currently implements nullref which is the bottom type for the any hierarchy. The other two bottom types need to be added as well.
