HxOverrides undefined or missing members unless --dce set to no

[thomasjwebb]

When doing operations involving modulo (because python has a non-standard implementation, I'm guessing) the haxe-generated Python code uses HxOverrides.mod to replace python's %. In one of my projects, I had to add --dce no to prevent this from happening when running the output using the python interpreter:

AttributeError: type object 'HxOverrides' has no attribute 'mod'

I tried to make a more minimal example to illustrate the problem and it instead will not even define HxOverrides unless I use --dce no.

Minimal example

Main.hx

package;

class Main
{
    public static function main() {
        var a:Int = -5;
        a = a % 7;
        trace(a);
    }
}

This is with the latest haxe (4.3.3) so it should have fixes for similar issues I've seen in closed issues.

The problem here was that the analyzer changed this to a %= 7 and DCE didn't check that particular pattern.
