All of our ICU workaround code honestly makes me want to cry, but r=me. 😅

> Source/JavaScriptCore/ChangeLog:18
> +        This is workaround, and still this workaround is not complete since we could have many variants. In that case, uloc_addLikelySubtags / uloc_minimizeSubtags
> +        still fails, and in that case, for now, we give up performing uloc_addLikelySubtags / uloc_minimizeSubtags. Fixing this needs to be
> +        done in ICU side.

We should create a JIRA ticket for this.

Let's use less cryptic variable names.
