--- Comment #35 from Robin Dapp <rdapp at gcc dot gnu.org> ---
What does get rid of the comparison failures in the three last posted reduced
examples is:

          gcall *call = dyn_cast<gcall *> (op_use_stmt);
          internal_fn ifn;
          if (call && gimple_call_internal_p (call))
            {
              ifn = gimple_call_internal_fn (call);
              unsigned else_pos = internal_fn_else_index (ifn);
              for (unsigned int j = 0; j < gimple_call_num_args (call); ++j)
                {
                  if (j == else_pos)
                    continue;
                  if (gimple_call_arg (call, j) == op.ops[opi])
                    cnt++;
                }
            }

i.e. ignoring the else altogether.
