[Bug middle-end/23606] New: fold does not fold (type)(a == b) into a == b (with type as the type)

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

I don't have a testcase for this one as convert already does it though with my tree combiner (or when 
TER folds), you can reproduce it with:

int f(int i, int j)
{
  _Bool a = i == j;
  int t = a;
  return t;
}
