RFR: 8191562: Missing include in gcArguments.cpp breaks minimal JVM build

David Holmes reported build failures in minimal JVM due to missing 
include in gcArguments.cpp:

https://bugs.openjdk.java.net/browse/JDK-8191562

This should fix it:

<http://cr.openjdk.java.net/%7Erkennke/8191562/webrev.00/>

Unfortunately, the minimal JVM doesn't build at all for me (*), so I am 
posting this blindly. However, it seems fairly obvious that it's 
correct: UNSUPPORTED_OPTION is defined in arguments.hpp, including it 
should fix the build failure.

Ok to go?
