[Bug middle-end/41435] New: GCC doesn't fold complex int division

["ghazi at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

For integral complex types like complex int, GCC doesn't fold division with
constant arguments.  E.g. this testcase should evaluate at compile-time and
link without any errors but doesn't:

extern void link_error(void);
#define EXPR ((2 + 4i) / 2)
int main(void)
{
  if (__real EXPR != 1 || __imag EXPR != 2)
    link_error();

  return 0;
}
