<i18n dev> RFR: 8349883: Locale.LanguageRange.parse("-") throws ArrayIndexOutOfBoundsException [v2]

[Justin Lu]

> Please review this PR which prevents a (non-specified) `AIOOBE` from leaking out of the range accepting endpoints in `Locale.LanguageRange`.
> 
> In the reported error case, the invalid range is a lone "-" which is `split` into an empty array. Checking if the range ends with "-" first, avoids indexing the empty array.

Justin Lu has updated the pull request incrementally with one additional commit since the last revision:

  Naoto's review - Include test in LanguageRangeTest instead. Additionally, bundle existing LRToString test into LanguageRangeTest as well
