[hl] `--dce full` and a call before `super` produce JIT ERROR

```haxe
class CustomException extends haxe.Exception {

public static function init() {
}

//adding `@:keep` fixes the error
public function new() {
super(fun());
}

// adding `inline` fixes the error
static function fun():String {
return 'hello';
}
}

class Main {
static function main() {
CustomException.init();
}
}
```
```
$ haxe --main Main --hl test.hl --dce full && hl test.hl
JIT ERROR -1 (jit.c line 1495)
