  Returns abrupt completions from ToString(flags)

  String.prototype.replaceAll ( searchValue, replaceValue )

  1. Let O be RequireObjectCoercible(this value).
  2. If searchValue is neither undefined nor null, then
    a. Let isRegExp be ? IsRegExp(searchString).
    b. If isRegExp is true, then
      i. Let flags be ? Get(searchValue, "flags").
      ii. Perform ? RequireObjectCoercible(flags).
      iii. If ? ToString(flags) does not contain "g", throw a TypeError exception.
