Comment (by SergeyBiryukov):

 Issues like this can happen once in a while due to an incomplete upgrade,
 when new files were added to core but failed to be copied properly, or
 when the `wp-settings.php` file that loads them failed to update for some
 reason.

 I believe this is a support issue, and there are no actionable items for
 core here at this time.
