Compares two regex_iterators.

| rhs | - |  a regex_iterator to compare to  | 
For the sake of exposition, assume that regex_iterator contains the following members:
BidirIt begin; BidirIt end; const regex_type *pregex; std::regex_constants::match_flag_type flags; std::match_results<BidirIt> match; true if *this and rhs are both end-of-sequence iterators, or if all of the following conditions are true: begin == rhs.begin end == rhs.end pregex == rhs.pregex flags == rhs.flags match[0] == rhs.match[0]
!(*this == rhs)
