 It would be handy if `dead_db()` could be made trappable always, either
 through using `wp_die()` instead of `die()` in the terse case, or via a
 filter.

 It currently causes WP-CLI (see https://github.com/wp-cli/wp-
 cli/pull/4303) to resort to a brittle hack in order to trap database
 connection errors.
