Since script is loaded using HTTP, why not use already defined CORS 
headers on server side while serving those scripts?
And if you want it to be defined in JS file itself, I'll suggest "use 
strict" approach:

file> ---------------------------------------------------------------
"Access-Control-Allow-Origin: *";
(function(){
     "use strict";
       var x = 5;
})();
---------------------------------------------------------------<file

and define CORS headers as a string (maybe with the restriction that 
those headers must be first executable/runnable code in JS file - so 
there may be comments and whitespaces before)
