aarch64: Add GCS support to the unwinder
Follows the current linux ABI that uses single signal entry token
and shared shadow stack between thread and alt stack.
Could be behind __ARM_FEATURE_GCS_DEFAULT ifdef (only do anything
special with gcs compat codegen) but there is a runtime check anyway.
Change affected tests to be compatible with -mbranch-protection=standard
libgcc/ChangeLog:
* config/aarch64/aarch64-unwind.h (_Unwind_Frames_Extra): Update.
(_Unwind_Frames_Increment): Define.
