Hmm, this one doesn't have a trace method. Where is this used, I would expect a
compile-time error because the trace method cannot be found. Is it unused? Can
we just delete it?

It isn't used as a Member nor Persistent on any other 'host object', but apart
from being able to directly construct it in scripts (new FormData()), form
submission code creates an instance while constructing the payload.

Will fix.

-    static PassRefPtr<DOMFormData> create(HTMLFormElement* form) { return adoptRef(new DOMFormData(form)); }
-    static PassRefPtr<DOMFormData> create(const WTF::TextEncoding& encoding) { return adoptRef(new DOMFormData(encoding)); }
