[jdk24u] RFR: 8353237: [AArch64] Incorrect result of VectorizedHashCode intrinsic on Cortex-A53

Tue May 27 08:00:35 UTC 2025

Fixes Cortex A53 regression in 24. While the patch is fairly recent, it is also predicated on A53 "feature", so all other AArch64 code is not affected. We have seen customer reports that current 21.0.7 is broken without this patch on A53, we expect 24 is also broken.

Testing:
 - [ ] GHA
