<pre>In <a href="https://godbolt.org/z/zTm190">https://godbolt.org/z/zTm190</a> the first std::visit gets folded and
eliminated, however the second within the loop does not. Analysis shows that
the optimizer doesn't constant fold the "vtable" access in the loop, while it
does without the loop.</pre>
