    Update gdb.ada/attr_ref_and_charlit for gnat-llvm
    
    This patch changes the gdb.ada/attr_ref_and_charlit test to come
    closer to passing with gnat-llvm.  This mostly works around some
    existing problems in gnat-llvm, but since the changes are harmless and
    help reduce the noise in the test results, I thought it would be
    better to land this.
    
    Because this is Ada-specific, I am checking this in.
