JDK 8 RFR, redux, for JDK-8005294 : Consider default methods for additions to AnnotatedElement

[Joe Darcy]

Hello Joel and Peter,

Working in previous feedback, please review the revised code changes for

     JDK-8005294 : Consider default methods for additions to 
AnnotatedElement
     http://cr.openjdk.java.net/~darcy/8005294.4/

I think the versions of getAnnotationsByType and getDeclaredAnnotation 
in this patch are solid, but getDeclaredAnnotationsByType may require 
some more refinement. (The asserts in getDeclaredAnnotationsByType are 
commented out since I was getting a bad build as a result; I'm following 
up with the HotSpot team.)

Also new in this version, the test program fleshed out.

Thank,

-Joe
