They have a two special sub nodes, one for the "helper" and one for
"for identifier". Otherwise they are treated as class/object/....

unit components/codetools/finddeclarationtool.pas
The codetools searches backwards recursively until an identifier is
found. So normally it can skip most code and simply compare the names of
types. The result issored in a cache for later searches.
With helpers this system no longer works.
