e739d54f86 [libcxx] Add std::any 
Summary:
This patch adds std::any by moving/adapting <experimental/any>.

This patch also implements the std::any parts of p0032r3 (http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0032r3.pdf)
and LWG 2509 (http://cplusplus.github.io/LWG/lwg-defects.html#2509).

I plan to push it in a day or two if there are no comments.

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.

3e9545e035 Update status of already completed Oulu issues. 
* P0163r0: Implemented in r273839.

* LWG 2309: pthread_mutex_lock only returns this error if certain debug flags
  were passed during construction. libc++ does not pass these flags. There is
  nothing to do.

* LWG 2310: Wording fix. No impact on libc++'s implementation.

* LWG 2312: libc++'s std::tuple implementation already constrains the overloads
  based on the number of arguments.

* LWG 2549: libc++'s std::tuple already applied this fix.

* LWG 2674: libc++ already depends on this relaxed wording.

* LWG 2704, 2706, 2707, 2719, 2720, 2721, 2723, 2725, 2728: All of these filesystem were either
  submitted by me and fixed before submission, or have already been applied.

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.

fe6d50fcaa Implement LWG issue 1169. num_get not fully compatible with strto* 
Use strtof and strtod for floats and doubles respectively instead of
always using strtold. The other parts of the change are already implemented
in libc++.

This patch also has a drive by fix to wbuffer_convert::underflow() which
prevents it from calling memmove(buff, null, 0).

10b52a0e56 Implement variadic lock_guard. 
Summary:
This patch implements the variadic `lock_guard` paper. 

Making `lock_guard` variadic is a ABI breaking change because the specialization `lock_guard<_Mutex>` mangles differently then when it was the primary template. This change only provides variadic `lock_guard` in ABI V2 or when `_LIBCPP_ABI_VARIADIC_LOCK_GUARD` is defined.

Note that in ABI V2 `lock_guard` must always be declared as a variadic template, even in C++03, in order to keep the ABI consistent. For this reason `lock_guard` is forward declared as a variadic template in all standard dialects and therefore depends on variadic templates being provided as an extension in C++03. All supported versions of Clang and GCC provide this extension.
