RFR: JDK-8313781: Add regression tests for large page logging and user-facing error messages [v4]

[Thomas Stuefe]

> In preparation for the UseSHM removal (https://bugs.openjdk.org/browse/JDK-8310841) I'd like more regression tests. 
> 
> The new test basically checks the behavior of the JVM when confronted with different variations of:
> - OS capabilities
> - JVM settings.
> 
> For example: If the JVM is started with -XX:+UseLargePages, but on the OS side there are no huge pages configured, or the kernel does not even support hugepages, the JVM should disable large pages and issue a warning.
