35d2fcfc8e Teach libc++ about the addressof() overloads it needs to work with 
Objective-C Automatic Reference Counting, where Objective-C object
pointers can have several different qualifiers (__strong, __weak,
__autoreleasing, __unsafe_unretained). These addressof() overloads are
only provided in ARC mode, and the __weak variant is conditionalized
on having weak-reference support in the ARC runtime.

For historical reasons, Clang provides these definitions itself, and
defines the macro _LIBCPP_PREDEFINED_OBJC_ARC_ADDRESSOF to note when
it as done so. The code belongs here, and this redundancy will be
eliminated in the future.

Addresses <rdar://problem/9658274>.

18884f4e9f Second try at getting noexcept on move and swap for deque. I changed std::alloctor to propagate_on_container_move_assignment so as to make deque<T> move assignment noexcept. What we really need is a compile-time switch that says an allocator always compares equal.

1694d23e23 noexcept for <memory>. I've added a few extension noexcept to: allocator_traits<A>::deallocate, allocaate<T>::deallocate, return_temporary_buffer, and default_delete<T>::operator()(T*) const. My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default|

e003ce4899 __invokable and __invoke_of now check for incomplete types and issue a compile-time diagnostic if they are used with incomplete types for anything except a return type. Note that both arguments *and* parameters are checked for completeness.

1468b668aa N3142. Many of these traits are just placeholders with medium quality emulation; waiting on compiler intrinsics to do it right.

28dbbe0596 Dave Zarzycki showed how the efficiency of shared_ptr could be significantly 
increased.  The following program is running 49% faster:

#include <iostream>
#include <memory>
#include <chrono>
#include <vector>
#include "chrono_io"

int main()
{
    typedef std::chrono::high_resolution_clock Clock;
    Clock::time_point t0 = Clock::now();
    {
        std::shared_ptr<int> p(new int (1));
        std::vector<std::shared_ptr<int> > v(1000000, p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
    }
    Clock::time_point t1 = Clock::now();
    std::cout << (t1-t0) << '\n';
}

36cdf027d2 I am experimenting with putting visibility-default attributes on all struct/classes in libc++. This checkin decorates only basic_string and vector as an experiment, and for review by those in this audience that might know more about visibilty than I do. If I get no negative feedback on this procedure I will begin to decorate the entire library in this way.

73d21a4f07 Changed __config to react to all of clang's currently documented has_feature flags, and renamed _LIBCPP_MOVE to _LIBCPP_HAS_NO_RVALUE_REFERENCES to be more consistent with the rest of the libc++'s flags, and with clang's nomenclature.
