Subject: [PATCH] LibJS: Add test case for locales which do not define day
 periods

Some locales do not define morning, night, etc. day period ranges.
TR-35 states they should fall back to the fixed day periods AM and PM.
Add a test case for the "as" locale, which is one such locale, to ensure
its AM/PM symbols are used.
