Note: We keep locale parsing and syntactic validation as-is. ECMA-402 places additional restrictions on locales above what is required by the Unicode spec. ICU doesn't provide methods that let us easily check those restrictions, whereas LibLocale does. Other browsers also implement their own validators here. This introduces a locale cache to re-use parsed locale data and various related structures (not doing so has a non-negligible performance impact on Intl tests). The existing APIs for canonicalization and display names are pretty intertwined, so they must both be adapted at once here. The results of canonicalization are slightly different on some edge cases. But the changed results are actually now aligned with Chrome and Safari.
