Add coverage for:

  • Return collations are supported by Intl.Collator.
  • Language subtag is und.
  • Language subtag has more than three letters.
  • Output array is sorted.

Also update existing test meta data to match current spec text and simplify checks in "output-array-values.js"

  • output-array-is-sorted.js fails in JSC, because JSC doesn't sort the output array.
  • preferred-from-unicode-extension-true-empty.js fails in JSC and V8 because of an ICU4C-related issue.
