abstract @:to order issue

```haxe
abstract Abstract(Dynamic) {
@:from public static inline function fromObject(v:Dynamic) { return cast v; }
@:to public inline function toInt():Int return cast this;
@:to public inline function toFloat():Float return this;
}
```
Main.hx
```haxe
var a:Abstract = 0;
var f:Float = a; // [cpp] Float f = ( (Float)(( (int)(a) )) );
var i:Int = a; // [cpp] int i = ( (int)(a) );
```

After reversing order of toInt and to toFloat implicit casts:

```haxe
var a:Abstract = 0;
var f:Float = a; // [cpp] Float f = ( (Float)(a) );
var i:Int = a; // [cpp] int i = ( (int)(a) );
```

Is there any documentation about priority of implicit casts? I found for array access on abstracts to be top to bottom, while for implicit casts seems to be reversed.
