Please review the fix for

     JDK-8212081 : AnnotatedType.toString implementation don't print 
annotations on embedded types
     http://cr.openjdk.java.net/~darcy/8212081.1/

A few notes on the test, the main structural change is that information 
about the expected properties of the toString form of the AnnotatedType 
of a method's return type is stored in a *declaration annotation* on the 
method. The presence of the expected number of type annotations on the 
full string of the AnnotatedType can thus be directly tested.
