Log:
    PR libstdc++/58659
    * include/bits/shared_ptr_base.h (__shared_count::__shared_count(P,D)):
    Delegate to constructor taking allocator.
    (__shared_count::_S_create_from_up): Inline into ...
    (__shared_count::__shared_count(unique_ptr<Y,D>&&): Here. Use
    std::conditional instead of constrained overloads. Allocate memory
    using the allocator type that will be used for deallocation.
    * testsuite/20_util/shared_ptr/cons/58659.cc: New.
    * testsuite/20_util/shared_ptr/cons/43820_neg.cc: Adjust.
