Hi all,

Please review this patch to reimplemente @require vm.gc.Z and 
WB_IsGCSupported to use a more precise check on Windows.

https://cr.openjdk.java.net/~stefank/8235760/webrev.01/
https://bugs.openjdk.java.net/browse/JDK-8235760

With this patch we call into the VM and try to resolve the required 
Windows APIs, instead of doing string comparisons on system properties.

Thanks,
StefanK
