You're acting like this is a gotcha, but the answer is obviously "all of them" and that indeed, this tells you interesting things about the behavior of your compiler. There are lots of variant scores in the linked article that reflect different ways of expressing the problem.
But also, it tells you something about the limitations of your language too. For example, the biggest single reason that C/C++ (and languages like Fortran/Zig/D and sometimes C# and Rust whose code generation is isomorphic to them) sit at the top of the list is that they autovectorize. SIMD code isn't a common idiom either, but the compiler figures it out anyway.
And apparently Haskell isn't capable of doing enough static analysis to fall back to an unboxed implementation (though given the simplicity of this code, that should be possible I think). That's not a "flaw" and it doesn't mean Haskell "loses", but it absolutely is an important thing to note. And charts like this show us where those holes lie.
