Walter and I discussed what auto ref for templates should look
like and reached the conclusion that an approach based on
lowering would be best. I added a proposed lowering to

I have to concur with Manu's statement in the PR. IMO `auto ref`
(i.e. the status quo) is a hack introduced because of the lack of
usable `scope`. We shouldn't spread it to other parts of the
language, at least not for rvalue references. `scope ref` is the
perfect fit for those.
(There may still be a use for `auto ref` with the meaning "pass
this as efficiently as possible, I don't care whether it's a
reference or not", but I'm not convinced of that either.)
