Because the unordered containers now have noexcept move constructors
it is no longer necessary to ensure that is_copy_constructible depends
on the value_type, so remove that kluge.

       * include/bits/alloc_traits.h (__allow_copy_cons): Remove.
       (__check_copy_constructible): Likewise.
       * include/bits/unordered_map.h (unordered_map, unordered_multimap):
       Do not derive from __check_copy_constructible.
       * include/bits/unordered_set.h (unordered_set, unordered_multiset):
       Likewise.
       * testsuite/23_containers/unordered_map/55043.cc: It is no longer
       necessary for is_copy_constructible to be correct to use nested
       unordered containers.
       * testsuite/23_containers/unordered_multimap/55043.cc: Likewise.
       * testsuite/23_containers/unordered_set/55043.cc: Likewise.
       * testsuite/23_containers/unordered_multiset/55043.cc: Likewise.


Tested x86_64-linux, committed to trunk.
