1. make Visitor not satisfy WideningTransformer …

   Visitors that satisfy WideningTransformer turn out to be measurably slower than
   WideningTransformer's themselves. This commit makes Visitor independent of
   WideningTransformer for a nice speed boost.
   
   Steps to recreate the bulk of this patch:
   
   1. Open the nodes in vi:
       vi `grep -l 'shared actual Result transform' * \
           | grep -v SelfReference`
   
   2. Record a macro:
       - qq // start recording
       - /shared actual Result transform // find transform()
       - <shift-v>jjy // highlight & copy
       - jj // move down
       - p // paste
       - DAshared actual void visit(Visitor visitor)
       - <esc>j
       - :s/transformer/visitor
       - :s/transform/visit
       - jhhhD // whitespace
       - q // stop recording
   
   3. Undo changes (uuuuuuuuuuuuu)
   
   4. Move to top of file (:1)
   
   5. Execute macro on all files:
       :bufdo execute "normal @q" | write
   
   6. :q
   
   7. Manually fix
       - SelfReference.ceylon
       - Identifier.ceylon
