dereferenceable to avoid check on lower_bound result.
(_Prime_rehash_policy::_M_bkt_for_elements): Call latter.
(_Prime_rehash_policy::_M_need_rehash): Likewise.

max value when reaching highest prime number.

being now useless.
* testsuite/23_containers/unordered_set/hash_policy/71181.cc: New.
* testsuite/23_containers/unordered_set/hash_policy/power2_rehash.cc
