8260704: ParallelGC: oldgen expansion needs release-store for _end

[omikhaltsova]

I'd like to backport JDK-8260704 to jdk13u for parity with jdk11u.
The original patch applied manually due to the slight context changes. This patch is identical to the same one applied to jdk11u. And, as in the patch for jdk11u, here the method from OrderAccess is used instead of Atomic because this method was moved from OrderAccess to Atomic only in JDK 14 with JDK-8234562.
All regular tests passed.
