Intl.getCanonicalLocales is not available on IE11, and therefore we used to rely on
Intl.NumberFormat.supportedLocalesOf to polyfill this method.
However, when used together with UnifiedNumberFormat polyfill, this causes an infinite
recursion loop because UnifiedNumberFormat.supportedLocalesOf will eventually call into
Intl.getCanonicalLocales! This diff puts a stopgap by using Intl.DateTimeFormat instead,
since it is not polyfilled by formatjs.
Fixes #543
