Request for review: JDK-8134569 : Add tests for prototype callsites

[Hannes Wallnoefer]

Please review JDK-8134569 : Add tests for prototype callsites:
http://cr.openjdk.java.net/~hannesw/8134569/

This just adds a few (passing) tests for prototype setups that I found 
missing in our test suite.

Thanks,
Hannes
