The program

void main()
{
  signed char i, j;
  i = j;
  i += 1;
}

yields a goto program:

signed char i;
signed char j;
i = j;
(signed int)i = (signed int)i + 1;

Broken since e78e7d1

See also #4209.

Doing so during goto-program conversion will ensure we can generate appropriate
conversion checks.
