    [Intl] Optimize Intl.Collator · 363fe1eb
    Sathya Gunasekaran authored
    This patch ports most of the Intl.Collator from JS to C++.
    
    The Intl.Collator object no longer stores all the resolved
    values. Instead these are looked up on demand as part of
    Intl.Collator.prototype.resolvedOptions(), saving several words. In
    the future, we can cache the result of the resolvedOptions as well.
    
    In this patch, we use ICU to do parsing of the unicode extension in
    the bcp47 language tag instead of using a custom extension parser.
    
    This patch also fixes several spec compliance bugs as well.
