merge revision(s) 4f19666e8b144600e959e4673f79d63f98bd637d: [Backport #16508]
`Regexp` in `MatchData` can be `nil`
`String#sub` with a string pattern defers creating a `Regexp`
until `MatchData#regexp` creates a `Regexp` from the matched
string. `Regexp#last_match(group_name)` accessed its content
without creating the `Regexp` though. [Bug #16508]
