Wrong type for some comparisons

[michael-schwarz]

For the following input

int main (int argc, char* argv[])
{
    signed char f2 = 7;
    signed char l_1857 = ((0xFFBD4A17L && f2) | f2);
}

CIL produces

int main(int argc , char **argv ) 
{ 
  signed char f2 ;
  signed char l_1857 ;
  {
#line 5
  f2 = (signed char)7;
#line 6
  l_1857 = (signed char )((f2 != (signed char)0) | (int )f2);
#line 7
  return (0);
}
}

The subexpression f2 != (signed char)0 in this has typ signed char, but the type should be int as for all comparisons in C.

This causes an error inside in Goblint where we assume comparisons have the correct type as mandated by the standard. References https://github.com/goblint/analyzer/pull/175
