--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Same as PR77705 but in this case the constructor functions should include the
locking/ref-counting dance (so we can optimize that as well).  Gets interesting
if we optimize multiple adjacent static inits with a single lock (do we?)
though
then we'd just make a wrapper that just contains the locking.
