155b681794 Reimplement is_constructible fallback implementation. Fixes PR21574. 
The previous implementation relied highly on specializations to handle
special cases. This new implementation lets the compiler do the work when possible.

5839fedf28 Implement C++17 tuple bits. Including apply and make_from_tuple. 
This patch upgrades <tuple> to be C++17 compliant by implementing:

* tuple_size_v: This was forgotten when implementing the other _v traits.
* std::apply: This was added via LFTS v1 in p0220r1.
* std::make_from_tuple: This was added in p0209r2.

053859ffc6 Flatten the tuple_element and __make_tuple_types implementations. 
This patch attempts to improve the QoI of std::tuples tuple_element and
__make_tuple_types helpers. Previously they required O(N) instantiations,
one for every element in the tuple

The new implementations are O(1) after __tuple_indices<Id...> is created.

This patch adds the weak_type typedef in shared_ptr. It is available in
C++17 and newer.

This patch also updates the _LIBCPP_STD_VER and TEST_STD_VER macros to
have the value of 16, since 2016 is the current year.

7838768593 Fix PR27115 - enable_shared_from_this does not work as a virtual base class. 
See https://llvm.org/bugs/show_bug.cgi?id=27115

The problem was that the conversion from
'const enable_shared_from_this<T>*' to 'const T*' didn't work if
T inherited enable_shared_from_this as a virtual base class. The fix
is to take the original pointer passed to shared_ptr's constructor in the
__enable_weak_this method and perform an upcast to 'const T*' instead of
performing a downcast from the enable_shared_from_this base.

abd892af3a Implement LWG 2488 - Make the placeholders constexpr. 
This patch makes the bind placeholders in std::placeholders both (1) const and
(2) constexpr (See below).

This is technically a breaking change for any code using the placeholders
outside of std::bind and depending on them being non-const. However I don't
think this will break any real world code.

(1) Previously the placeholders were non-const extern globals in all
dialects. This patch changes these extern globals to be const in all dialects.
Since the cv-qualifiers don't participate in name mangling for globals this
is an ABI compatible change.

(2) Make the placeholders constexpr in C++11 and beyond. Although LWG 2488 only
applies to C++17 I don't see any reason not to backport this change.

fa5a105971 Fix PR27684 - std::tuple no longer accepts reference to incomplete type in some cases. 
Libc++ has to deduce the 'allocator_arg_t' parameter as 'AllocArgT' for the
following constructor:

  template <class Alloc> tuple(allocator_arg_t, Alloc const&)

Previously libc++ has tried to support tags derived from 'allocator_arg_t' by
using 'is_base_of<AllocArgT, allocator_arg_t>'. However this breaks whenever a
2-tuple contains a reference to an incomplete type as its first parameter.
