RFR: 8324186: AARCH64: Use "dmb.ishst+dmb.ishld" for release barrier

[kuaiwei]

Details is https://mail.openjdk.org/pipermail/hotspot-compiler-dev/2024-January/071921.html.
Using a combined dmb.ish for release barrier will introduce a heavy storeload barrier. Use "dmb.ishst+dmb.ishld" pair instead, we can gain performance improvement on N1 and N2 architecture. The benchmark is test/micro/org/openjdk/bench/vm/compiler/FinalFieldInitialize.java
Run with ParallelGC to minimalize impact of gc barrier.

make test TEST="micro:org.openjdk.bench.vm.compiler.FinalFieldInitialize" MICRO="VM_OPTIONS=-XX:+UseParallelGC"
...
FinalFieldInitialize.testAllocWithFinal  thrpt    9  1411.601 ?  6.546  ops/s

Without the patch

FinalFieldInitialize.testAllocWithFinal  thrpt    9  1214.575 ? 14.217  ops/s
