RFR: 8280843: macos-Aarch64 SEGV in frame::sender_for_compiled_frame after JDK-8277948

[Denghui Dong]

Hi,

Could I have a review of this fix?

JDK-8277948 missed the changes to thread_bsd_aarch64.cpp and thread_windows_aarch64.cpp. It caused some tests failures.

I'm trying to find an environment for windows/mac on aarch64 for testing.

Thanks,
Denghui
