AnnotatedExpr suggestion

[Jonathan Gibbons]

Low priority suggestion:

The following in JCNewArray is mildly icky.


         public List<JCExpression> dims;
         // type annotations on dimensions
         public List<List<JCAnnotation>> dimAnnotations;

Would it make sense to introduce JCAnnotatedExpression so that that 
reduces to
       public List<JCAnnotatedExpression> dims;
