Comment (by ocean90):

 [attachment:26511.4.diff] looks good so far. Note that is uses
 `get_user_locale()` from #29783 which shouldn't be part of the initial
 commit. (Depends on which ticket lands first.)

 * Is there a reason why `$GLOBALS['wp_locale'] = new WP_Locale();` happens
 after the actions?
 * The docs for `WP_Locale_Switcher` can be improved:
    * 'Class for switching locales.' => 'Core class used for switching
 locales.'
    * 'Locale switcher object.' => 'Locale API: WP_Locale_Switcher class'
 * Is the `get_translations_for_domain()` call in
 `WP_Locale_Switcher::load_translations()` required? Tests are still
 passing when removing the line.
