    [Intl] Optimize Intl.PluralRules · cdb4d913
    Sathya Gunasekaran authored
    Previously, Intl.PluralRules was mostly implemented in JavaScript. This
    patch moves most of the constructor and parts of other methods to C++.
    
    The size of the Intl.PluralRules object is reduced by not storing
    MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits,
    MinimumSignificantDigits, MaximumSignificantDigits. Instead these are
    looked up from icu::DecimalFormat as required.
    
    Another optimziation is that we don't create the result of
    resolvedOptions when the Intl.PluralRules object is constructed, but
    instead defer until this method is called. In the future, we may want
    to cache the result.
    
    This patch also cleans up several error handling paths that shouldn't
    happen with ICU and instead just crashes should it ever happen.
