    gas: scfi: add missing ginsn-cofi-1 testcase files
    
    Previous commit a58dc5427f0 intended to bring the following two commits
    from master branch:
    
     91cdbed4d7b gas: scfi: untraceable control flow should be a hard error
     16cbeae1b27 x86: testsuite: scfi: adjust COFI testcase
    
    But missed adding the testcase files. Fix the failure by adding the
    missing files.
    
    gas/testsuite/
            * gas/scfi/x86_64/ginsn-cofi-1.l: New test.
            * gas/scfi/x86_64/ginsn-cofi-1.s: Likewise.
