Not correct porting of string + int(int + int)

[andrew-git]

c, d - Int as3 code for example:

package {
    public class Issue {
        public function Issue() {
            a = "b" + int (c + d);
        }
    }
}

expected result

class Issue
{
    public function new()
    {
            a = "b" + (c + d);
    }
}

actual result

class Issue
{
    public function new()
    {
            a = "b" + c + d;
    }
}
