Integrated: 8317660: [BACKOUT] 8269393: store/load order not preserved when handling memory pool due to weakly ordered memory architecture of aarch64

[Tobias Hartmann]

Please review this clean backout of [JDK-8269393](https://bugs.openjdk.org/browse/JDK-8269393) because we see `Attempting to acquire lock CodeCache_lock/nosafepoint-2 out of order with lock Notification_lock/service -- possible deadlock` asserts with several tests.

Thanks,
Tobias
