    Reland "[wasm-gc] Implement call_ref on WasmJSFunction" · 40ad9116
    Manos Koukoutos authored
    This is a reland of 6227c95e
    
    Fixes compared to original landing:
    - Decode a WASM_TO_JS_FUNCTION Code object as a WASM_TO_JS frame.
    - Enable call_ref on WasmJSFunctions with arity mismatch.
    - Use builtin pointer in BuildWasmToJSWrapper, to avoid having to
      resolve the relocatable constant.
