<pre>Test case here:
<a href="https://godbolt.org/g/6apogL">https://godbolt.org/g/6apogL</a>
Although the `mask_add256_avx512vl` function uses a mask intrinsic, it produces
the same code (and I think the same IR) as the `mask_add256` function, which
doesn't. (I wasn't able to get clang to emit masked ymm instructions at all).</pre>
