This corresponds to commit 9278a14cf406f8edb5052c42b83750112bf5b515
in dav1d.
Omitting the C-only functions doesn't speed up benchmarking
anyway (as those has to be benchmarked before we know if we have
any corresponding assembly functions), and being able to benchmark
those functions without corresponding assembly can be valuable in
a number of cases.
