Should we issue a warning if the loaded version is < 2? |

Probably not. Users tend to complain about those. :-) |

Thanks @marcandre. This unblocks me in a major way. |

Follow rubocop#9154, rubocop#9155, and rubocop#9102. This is a step towards the widespread use of regexp_parser 2.0. RuboCop core accepts regexp_parser 1.8, but several code is already incompatible with regexp_parser 1.8. It can cause issue because these combination of versions. Therefore, this PR ports code for regexp_parser 1.8 that will never be maintained from rubocop#9102. Implementation of this patch, code is intentionally duplicated because it is evaluated only when the class is defined. Also, since obsoleted code for regexp_parser 1.8 is assumed to never be maintained, the target to be removed is clear. To be honest, it's ugly as implementation, but I think it has the least impact for RuboCop 1.x series users.
