Description Asumu Takikawa 2023-03-29 14:46:56 PDT 
Currently JSC implements the cast operations ref.cast and ref.test, but does not implement the control versions br_on_cast and br_on_cast_fail.

Note: the validation for these instructions is going to change slightly in the near future I believe (https://github.com/WebAssembly/gc/pull/359/)
