Issue use -m system, systemjs cant handle duplicate dependence, They have deleted it

[LinboLen]

systemjs when there are duplicate dependence in system.register entry,
the problem occur because the below systemjs function

function dedupe(deps) {
  var newDeps = [];
  for (var i = 0, l = deps.length; i < l; i++)
    if (indexOf.call(newDeps, deps[i]) == -1)
      newDeps.push(deps[i])
  return newDeps;
}

They really delete dumplicate dependence, and the system.register dependence array length can't match the setter array then I see a lot of red in my console... ...
