[jdk17u-dev] RFR: 8350412: [21u] AArch64: Ambiguous frame layout leads to incorrect traces in JFR

[Dmitry Chuyko]

This tiny change fixes incorrect stack traces sometimes reported by JFR (non-deterministic stack walking). It is a backport from jdk21u. The pach has been manually recreated in 17u context (there are no post_call_nop() calls - a part of Virtual Threads, and max_vector_size comparison is different - a part of SVE support), in principal the patch is the same.

Testing: tier1,2 on linux-aarch64.
