    aarch64: Add testcase for PR97405
    
    This aarch64 sve specific code was fixed by r15-917-gc9842f99042454
    which added a riscv specific testcase so adding an aarch64 one to test
    the fix does not regress is a good idea.
    
    Committed as obvious after testing the testcase for aarch64-linux-gnu.
