Description

When opening a TCA Form of e.g. a tt_content record of sys_language_id 0 the l18n_parent field is processed, though the field isn't even displayed.

If you v a lot of tt_content records on the same pid this leads to major performance issues.

E.g. if arround 45k tt_content records on the same pid which are used by a container record via IRRE (kind of like the news does).

If there r 10 Records attached to the container records that leads to 10x45k interations in TYPO3\CMS\Backend\Form\FormDataProvider\AbstractItemProvider\addItemsFromForeignTable which takes 40sec. On my maschine :).

The only way to get arround this is to set type=>none to l18n_parent via override.

This behavior did not exist in TYPO3 6.1 (not sure about later versions).
I assume it has been introduced by the rewriting of the whole tce/form stuff.

I think this is more a general issue, imho fields that r not displayed at all by e.g. DisplayCond should be filtered earlier so that dont make their way through the itemProvider.

Note: this issues is not restricted to tt_content. In general: fields are processed by itemProviders/Dataproviders no matter if they r acctually displayed/used or not.
