RFR: JDK-8035496: G1 ARM: missing remset entry noticed by VerifyAfterGC for vm/gc/concurrent/lp50yp10rp70mr30st0

[Bengt Rutisson]

Hi everyone,

Could I have a couple of reviews for this change to make G1 work 
correctly on non-TSO platforms?

https://bugs.openjdk.java.net/browse/JDK-8035496
http://cr.openjdk.java.net/~brutisso/8035496/webrev.00/

The change was contributed by Bertrand Delsart. I'm shepherding it into 
the JDK 9 repo.

Thanks,
Bengt
