Class file annotations duplicated on repeated runs of insert-annotations

[GoogleCodeExporter]

Save attached files and compile source (javac C.java).  Run the following 
command twice:

    insert-annotations C.class C.jaif

Examining the class file with javap (javap -v C.class) reveals that two 
identical RuntimeInvisibleTypeAnnotations attributes have been added to the 
annotated method.  If the annotation is already present, it should not be added 
again.  Otherwise, if the attribute already exists, insert-annotations should 
add to the existing attribute instead of creating a new one.
