RFR(S): 8159818: Convert IHOP_test to GTest

[Kirill Zhaldybin]

Thomas,

Thank you for reviewing the fix!

Here are a new WebRev: 
http://cr.openjdk.java.net/~kzhaldyb/webrevs/JDK-8159818/webrev.01/

Could you please let me know your opinion?

Changes:
1. g1IHOPControl.hpp copyright updated
2. static void test_update parameters list reformatted.
3. Comment "Test could be only run with G1" changed to "Test requires G1"
4. Some reviewers are pretty strict about 80 symbols. Could you please 
let me know if I need to change limit for the line lengths?

Thank you.

Regards, Kirill
