RFR: 8210683: Search result display order reversed for overloaded entries

Please review: 

Bug: https://bugs.openjdk.java.net/browse/JDK-8210683
Webrev: http://cr.openjdk.java.net/~hannesw/8210683/webrev.00/

Docs generated with patch applied:

Note that the new behaviour is to put the var-args signature last, whereas before var-args was in first position (even before the no-args signature).

Thanks,
Hannes
