<pre>__builtin_cpu_is and function multiversioning will fail to correctly detect
skylake-avx512 and cascadelake cpus without this. This code was broken in a
refactoring in June.
Unfortunately, we don't have a good way to test it since it the function
depends on executing CPUID on the host. We should really figure out a way to
mock this interface so we can write tests for this code.</pre>
