The __cpp_lib_constexpr macro is (now?) for a different feature.
The proposed resolution for https://cplusplus.github.io/LWG/issue3256
is to keep the __cpp_lib_constexpr_algorithms name to indicate support
for what is currently described by __cpp_lib_constexpr_swap_algorithms
(and see https://cplusplus.github.io/LWG/issue3257 for another issue
in this area).
