`TypeIterator` didn't handle `BoundMethodType`, so any impl lookup whose self type is a bound method crashed, for example `c.Get != 0` or `var x: i32 = c.Get;` after forgetting the call parentheses. Treat it as a concrete type, and as trivially destructible when checking `Destroy`, since bound methods are empty at runtime. These cases now produce the usual missing-impl diagnostics.
