Array.prototype.toLocaleString should use a locale-aware separator

Reported by silv3rw...@gmail.com, Aug 9 2017 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0

Steps to reproduce the problem:
1. run ['',''].toLocaleString() on a Windows machine with a german locale and default regional settings.

What is the expected behavior?
Output is ',', but should be ';'

What went wrong?
Chrome does not seem to check the system's locale setting in this case, while the spec [1] clearly states that "the list-separator String appropriate for the host environment’s current locale" should be used.

IE11 and presumably Edge output '; ' for the test case, while Firefox exhibits the same issue as Chrome [2].

Did this work before? No

There's some discussion about changing the specification here as part of the ListFormat proposal at ECMA 402 [1] but it doesn't seem to have made it into the current draft spec [2]. I don't know if CLDR has data like "," and ";"--I only see [3], which is more like what I would expect linguistically (e.g., there's a space after the punctuation mark in their English example); I don't quite understand when a bare "," or ";" would be appropriate for a language like English or German.
