    analyzer: add regression test for fixed ICE [PR94028]
    
    The C++ reproducer for PR analyzer/94028 generates a similar ICE
    to that of the Fortran reproducer for PR analyzer/93993 and, like
    it, was fixed by r10-7023-g3d66e153b40ed000af30a9e569a05f34d5d576aa.
    
    This patch adds the C++ reproducer as a regression test.
