Test canonicalisation within transformed extension subtags.

8.2.1 Intl.getCanonicalLocales (locales)
1. Let ll be ? CanonicalizeLocaleList(locales).
2. Return CreateArrayFromList(ll).
9.2.1 CanonicalizeLocaleList (locales)
...
7. Repeat, while k < len
...
c. If kPresent is true, then
...
v. If IsStructurallyValidLanguageTag(tag) is false, throw a RangeError exception.
vi. Let canonicalizedTag be CanonicalizeUnicodeLocaleId(tag).
