Reviewed by Anders Carlsson.

* CMakeLists.txt: Removed ValidityState.cpp.
* GNUmakefile.list.am: Ditto.
* WebCore.vcxproj/WebCore.vcxproj: Ditto.
* WebCore.vcxproj/WebCore.vcxproj.filters: Ditto.
* WebCore.xcodeproj/project.pbxproj: Ditto.

* html/FormAssociatedElement.cpp: Removed ValidityState.h include and the
FormAssociatedElement::validity function. That function is now an inline
in the ValidityState.h header.

* html/FormAssociatedElement.h: Added badInput function, the only function
from the ValidityState interface that was not already present here. Removed
m_validityState.

* html/HTMLFormControlElement.cpp: Removed include of ValidityState.h.
(WebCore::HTMLFormControlElement::isValidFormControlElement): Use the valid
function directly instead of indirectly through the validity state.
(WebCore::HTMLFormControlElement::setNeedsValidityCheck): Ditto.

* html/ValidityState.cpp: Removed.

* html/ValidityState.h: Removed the body of the ValidityState class and
made it effectively a "typedef" for FormAssociatedElement. It's actually
a derived class that adds no members, which is not quite right but will
work just fine for this.
(WebCore::FormAssociatedElement::validity): Implemented; just returns the
FormAssociatedElement, which the bindings expose as a ValidityState.

* html/ValidityState.idl: Use SkipVTableValidation instead of
ImplementationLacksVTable because FormAssociatedElement does have a vtable.
