RFR: 8170067: -XX:ExplicitGCInvokesConcurrentAndUnloadsClasses is not implemented for G1

[Erik Helin]

Hi everyone,

thanks for all your feedback!

Taking all the suggestions into account and discussing this patch with 
others, I now withdraw this review request. I now think it makes more 
sense to deprecate this flag, see 
http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2016-November/019314.html 
for details.

Thanks,
Erik
