Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd
and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to
update is utils/checkout_cloog.sh.

Instead of returning a pointer to the domain, we return a new copy of it. This
is safer, as we do not give access to internal objects. It is also not
expensive, as isl will just increment a reference counter.
