Both code variants produce exactly the same arrays.

With C++14, one is left as code that will be run at startup,
the other was successfully 'constexpr'-computed.

With C++17, the first variant is successfully 'constexpr'-computed too.

Both variants are clean as of -fsanitize=address,undefined,integer.
