Subject: Fix comment about AVX-512 popcount support.

Fix comment about AVX-512 popcount support.

Since commit f78667bd91, we've used __attribute__((target(...)))
instead of extra compiler flags for AVX-512 support, but this
comment still says that we put the code in a separate file because
it might require extra compiler flags.  Let's just remove that part
of the comment.
