Discussion:
std::reverse_iterator::reverse_iterator(Iterator) should be constexpr so that other constexpr functions can return reverse_iterators. Of the other methods, the other constructors, base(), operator+, operator-, operator[], and the non-member operators can probably also be constexpr.
operator* cannot be constexpr because it involves an assignment to a member variable. Discussion starting with c++std-lib-33282 indicated that it would be useful to make reverse_iterator a literal type despite this restriction on its use at compile time.
