Before, we allocated one script per function per instance, and each script referenced the wasm instance and the function index. Now we only allocate one script per compiled wasm module, so the script also only references this WasmCompiledModule, which causes changes to many interfaces. Instead of fixing the disassemble API only used via debug.js, I decided to drop it for now. Some later CL will reintroduce it via DebugInterface.
