Hi,

Please review this testfix to avoid the following issue:
https://bugs.openjdk.java.net/browse/JDK-8040935

Webrev:
http://cr.openjdk.java.net/~sjohanss/8040935/hotspot.00

Summary:
Making the test a driver test to avoid dealing with externally specified 
flags. One problematic flag is AggressiveOpts, it causes the VM to 
allocate more stuff during startup and that together with UseNUMA the 
eden space gets to little to handle all startup allocations. This will 
in turn lead to a GC being triggered before initialization is finished, 
and because of that failing the test.

Testing:
* Tested via JPRT

Thanks,
Stefan
