This is primarily done to support new `std::*_ordering` types, but the refactoring also supports any other type with this property. The compilation overhead is surprisingly low. Testing it with clang on a Linux machine, compiling our SelfTest project takes only 2-3% longer with these changes than it takes otherwise. Closes #2555
