This CL:
* Adds a "reordering fuzzing step", i.e. it tries to sort the fields,
procedures etc in both ascending order and descending order
to verify that there are on crashes and no changes in error vs
no error. This has been tested on http://dartbug.com/34803
before the fix landed.
* Introduces an attempt at "visiting the outline" of the "direct from
parser ast".
