Message:

I18N: Improve _load_textdomain_just_in_time() logic when there are no translation files.

Fixes a performance issue where the JIT logic is invoked for every translation call if the there are no translations in the current locale. With this change, the information is cached by adding Noop_Translations instances to the global $l10n array. This way, get_translations_for_domain() returns earlier, thus avoiding subsequent _load_textdomain_just_in_time() calls.

Props swissspidy, johnbillion, ocean90.
Fixes #58321.
