git branch -vv will show "gone" next to a remote tracking branch if it
does not exist. for-each-ref is suitable for parsing but had no way of
showing this information.
This introduces "%(upstream:gone)" to display "gone" in the formatted
output if the ref does not exist or an empty string otherwise, analogous
to git branch -vv.
