libstdc++: Always instantiate key_type to compute hash code [PR115285]
Even if it is possible to compute a hash code from the inserted arguments
we need to instantiate the key_type to guaranty hash code consistency.
Preserve the lazy instantiation of the mapped_type in the context of
associative containers.
libstdc++-v3/ChangeLog:
PR libstdc++/115285
* include/bits/hashtable.h (_S_forward_key<_Kt>): Always return a temporary
key_type instance.
* testsuite/23_containers/unordered_map/96088.cc: Adapt to additional instanciation.
Also check that mapped_type is not instantiated when there is no insertion.
* testsuite/23_containers/unordered_multimap/96088.cc: Adapt to additional
instanciation.
* testsuite/23_containers/unordered_multiset/96088.cc: Likewise.
* testsuite/23_containers/unordered_set/96088.cc: Likewise.
* testsuite/23_containers/unordered_set/pr115285.cc: New test case.
