Compares the underlying std::type_info objects.
1,2) Checks whether the underlying std::type_info objects refer to the same type.
| The != operator is synthesized from operator==. | (since C++20) |

[edit] Return value
true if the underlying std::type_info objects refer to the same type, false otherwise.
true if the underlying std::type_info objects refer not to the same type, false otherwise.
3-6) true if the types referred by the underlying std::type_info objects are ordered by corresponding order, false otherwise.
- std::strong_ordering::equal if the underlying std::type_info objects refer to the same type, otherwise std::strong_ordering::less if *this's underlying std::type_info object precedes rhs's in the implementation-defined ordering, otherwise std::strong_ordering::greater.
