I think it's easier to simply enforce the redirect and have everything be served over TLS. Once you do that, there's never any danger of parts that require TLS not actually getting it.
E.g., in nginx, I've got
listen 80 default_server;
listen [::]:80 default_server;
return 301 https://$server_name$request_uri;
and then I know everything is using TLS. (It seems llvm.org is using apache, but I imagine the apache directives are equally simple.) It seems significantly easier to maintain than needing to serve different content using HTTP vs. HTTPS.
As an added benefit, every connection tests your TLS configuration meaning that it's much easier to find problems such as expired certs. For example, https://llvm.org is using a cert with SHA-1 which it absolutely should not be doing in 2017. This shows up as insecure for me in Chrome.
(One can also make arguments about how all Internet traffic should be authenticated at the least, but I think the pure engineering argument that it's easier to just enforce it everywhere is the better argument.)
