        Forms with autocomplete=off should not consume saved state
        https://bugs.webkit.org/show_bug.cgi?id=36762

        Introduce Element::shouldSaveAndRestoreFormControlState() to check
        if we should save and restore control state.

        Test: fast/forms/state-restore-to-non-autocomplete-form.html

        * dom/Document.cpp:
        (WebCore::Document::formElementsState): Check shouldSaveAndRestoreFormControlState().
        * dom/Element.h:
        (WebCore::Element::shouldSaveAndRestoreFormControlState): Added. It just returns true.
        * html/HTMLFormControlElement.cpp:
        (WebCore::HTMLFormControlElementWithState::autoComplete):
          Added. It return autocomplete state of the form.
        (WebCore::HTMLFormControlElementWithState::shouldSaveAndRestoreFormControlState):
          Added. It returns the result of autoComplete().
        (WebCore::HTMLFormControlElementWithState::finishParsingChildren):
          Do not restore state if shouldSaveAndRestoreFormControlState() is false.
        * html/HTMLFormControlElement.h: Declare autoComplete() and overriding methods.
        * html/HTMLInputElement.cpp:
        (WebCore::HTMLInputElement::autoComplete):
          Reduce code by using autoComplete() of the parent class.
        (WebCore::HTMLInputElement::saveFormControlState):
          Remove the autoComplete() check. Document::formElementsState() does equivalent check.
