The following two functions should produce the same *.optimized file:
int t( int i)
{
  int j;
  if(i ==0)
  {
   j = 1;
   goto end;
  }
  j = 0;
end:
  return j;
}

int t1(int i)
{
  _Bool j1 = i == 0;
  return j1;
}

Other optimizations might be missed out by not doing this, I do not know.  Most likely 
what needs to happen is another temp then add the conversion.
