Most of our use of these compatibility macros went away with
041df69edd3 (Merge branch 'ab/fewer-the-index-macros', 2022-11-28) ,
which was part of v2.39.0.
That topic left out these stragglers, as some of this would have
conflicted with in-flight topics, and I'd skipped the cache-tree.h
cases altogether.
The update in v2 is trivial, just to rebase the series for changes on
"master". There are no semantic or textual conflicts with "seen"
either, so finishing this migration before we get another user of them
would be nice.
Yay.
Thanks.
