[TWR] AIOOB in compiler.codegen.ExceptionLabel.placeEnd when using try block with resources

Found during code review: This program triggers an AIOOB in `compiler.codegen.ExceptionLabel.placeEnd`

I could observe it all the way back to 4.15, but problem likely goes back much farther back in time:

```
public class X implements AutoCloseable {

public void close() throws Exception {}

public static void foo(String[] args) {

for (String arg : args) {
try (X x = new X()) {
if (args.length < 1) {
System.out.println("if");
break;
} else {
System.out.println("else");
break;
}
} finally {
System.out.println("finally");
break;
}
}
}

public static void main(String[] args) {
foo(new String[] { "Hello", "World" });
}
}
```
