    implregex: handle additional GRegex flags
    
    We want to use G_REGEX_OPTIMIZE to enable our JIT so that different
    subsystems can use different values here. For example, when porting the
    search context to use PCRE2, we will probably want to avoid using the JIT
    as some match options would not be available.
