RFR: JDK-8257959: Add gtest run with -XX:+UseLargePages

[Thomas Stuefe]

Hi,

may I please have reviews for this addition.

To better test changes in large page handling, it makes sense to regularly run gtests with large pages enabled. Not the whole gtest suite needs to be run, but at least the os* part.

Thanks, Thomas
