PR libstdc++/51608
* include/bits/hashtable_policy.h (_Equal_helper<>): New, change the
way the _Equal functor is used depending on whether hash code is
cached or not.
(_Ebo_helper<>): New helper type to introduce EBO when possible.
(_Hash_code_base): Use _Ebo_helper to limit memory footprint. Move
_Equal functor management...
(_Hashtable_base): ...here, new, use _Equal_helper.
(_Local_iterator_base<>, _Locale_iterator<>, _Locale_const_iterator<>):
New, use _Hash_code_base, implementation of...
* include/bits/hashtable.h (_Hashtable<>::local_iterator,
_Hashtable<>::const_local_iterator): ...those. Add static assertions
checking that some functors are empty depending on whether hash code
is cache or not.
(_Hashtable<>::_M_bucket_index): New overloads using current bucket
count, use through out the _Hastable<> implementation.
* include/bits/unordered_set.h (__unordered_set<>,
__unordered_multiset<>): Cache hash code iff hash functor is not
empty and not final.
* include/bits/unordered_map.h (__unordered_map<>,
__unordered_multimap<>): Likewise.
* include/debug/unordered_map
(unordered_map<>::_S_to_local, unordered_multimap<>::_S_to_local):
Adapt to match new local iterator implementation.
* include/debug/unordered_set (unordered_set<>::_S_to_local,
unordered_multiset<>::_S_to_local): Likewise.
* include/profile/unordered_map (unordered_map<>::_M_profile_destruct,
unordered_multimap<>::_M_profile_destruct): Enhance thanks to usage of
local iterators.
* include/profile/unordered_set (unordered_set<>::_M_profile_destruct,
unordered_multiset<>::_M_profile_destruct): Likewise.
* testsuite_files/23_containers/unordered_set/instantiation_neg.cc:
Fix error line.
* testsuite_files/23_containers/unordered_set/final_hash.cc: New.
* testsuite_files/23_containers/unordered_multiset/final_hash.cc: New.
* testsuite_files/23_containers/unordered_map/final_hash.cc: New.
* testsuite_files/23_containers/unordered_multimap/final_hash.cc: New.
