    aarch64: Add non-local goto and jump tests for GCS
    
    These are scan asm tests only, relying on existing execution tests
    for runtime coverage.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/aarch64/gcs-nonlocal-1.c: New test.
            * gcc.target/aarch64/gcs-nonlocal-1-track-speculation.c: New test.
            * gcc.target/aarch64/gcs-nonlocal-2.c: New test.
            * gcc.target/aarch64/gcs-nonlocal-2-track-speculation.c: New test.
            * gcc.target/aarch64/gcs-nonlocal-1.h: New header file.
            * gcc.target/aarch64/gcs-nonlocal-2.h: New header file.
