RFR JDK-8204938: Add a test case to automatically check the updated LSR data

[Nishit Jain]

Hi,

Please review the fix for JDK-8204938

Bug: https://bugs.openjdk.java.net/browse/JDK-8204938
Webrev: http://cr.openjdk.java.net/~nishjain/8204938/webrev.02/

Fix: Added a test case to cross check the LSR data generated for the JDK 
APIs. So, for each lsr data update, the test case need not be updated, 
it automatically cross checks the updated lsr data.

Regards,
Nishit Jain
