    Add 'c-c++-common/goacc/kernels-decompose-pr104086-1.c' [PR104086]
    
    ..., currently XFAILed with 'dg-ice', as it runs into
    'gcc/omp-low.cc:lower_omp_target':
    
        13125                       else if (is_gimple_reg (var))
        13126                         {
        13127                           gcc_assert (offloaded);
    
    This means, the recent PR100280 etc. changes are still not sufficient.
