/* Reproducer for PR jit/66779.

   Inject the equivalent of:
     T FUNCNAME (T i, T j, T k)
     {
       bool comp0 = i & 0x40;
       bool comp1 = (j == k);
       if (comp0 && comp1)
	 return 7;
       else
	 return 22;
     }
   for some type T; this was segfaulting during the expansion to RTL
   due to missing handling for some machine modes in
   jit_langhook_type_for_mode.  */
