In general, we put changes like this behind a flag. The plugin is bundled with
clang, so this will have an effect the next time we roll clang. Rolling clang is
already very hard, so we don't want to be blocked on a certain directory having
to be plugin-clean for the roll. So put this behind a flag, wait for the roll,
then toggle the flag async after the roll. (And then the flag can be removed
again.)

Sure, will do shortly.
