description: Behavior when regexp[@@matchAll] is undefined or null
info: |
String.prototype.matchAll ( regexp )
1. Let O be ? RequireObjectCoercible(this value).
2. If regexp is neither undefined nor null, then
a. Let matcher be ? GetMethod(regexp, @@matchAll).
b. If matcher is not undefined, then
[...]
3. Let S be ? ToString(O).
4. Let rx be ? RegExpCreate(R, "g").
5. Return ? Invoke(rx, @@matchAll, « S »).
