In JavaSCript implementations that supports ECMA-402,
`Array.prototype.toLocaleString()` must invoke the `toLocaleString` method of
each non-undefined, non-null elements witch exactly two (2) arguments.
See: https://tc39.es/ecma402/#sup-array.prototype.toLocaleString step 6.c.i.
V8 appears to provide no arguments when locale is undefined and to not provide options when options is undefined.
