`@param` should not error in JS when the function uses `arguments`

[sandersn]

Code

// @lib: dom,es5,es6
// @target: es6
// @noEmit: true
// @allowJs: true
// @checkJs: true
// @Filename: a.js
/**
 * @param {string} first
 */
function concat(/* first, second, ... */) {
  var s = ''
  for (var i = 0; l = arguments.length; i < l; i++) {
    s += arguments[i]
  }
  return s
}

Expected behavior:
No error.

Actual behavior:
Errors on each of the parameters.
