Hi all,

Could I have a couple of reviews for this tiny change for OldPLABSize flag?

We would face an assert complaining too large array size based on 
OldPLABSize.
And we already have a constraint for this flag checking same 
value(ThreadLocalAllocBuffer::max_size) but the constraint function is 
checking for CMS GC and G1 GC.
This change is just adding parallel gc on that check routine to limit 
both min and max.

CR: https://bugs.openjdk.java.net/browse/JDK-8153201
Webrev: http://cr.openjdk.java.net/~sangheki/8153201/webrev.00
Testing: JPRT, runtime/commandline JTREG tests for all platforms.

Thanks,
Sangheon
