Description Asumu Takikawa 2022-07-01 13:24:48 PDT 
The Wasm GC proposal (https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md) has a notion of "i31refs", which are a 31-bit integer type that shares its representation with other reference types. It can be used for compiling languages that need a uniform representation for both unboxed integers and compound types.

This bug is for the type representation for i31refs and adding i31ref as a new reference type.
