Mehdi Amini e9c66ad9fa Add markup for libc++ dylib availability 
Libc++ is used as a system library on macOS and iOS (amongst others). In order
for users to be able to compile a binary that is intended to be deployed to an
older version of the platform, clang provides the
availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_
that can be placed on declarations to describe the lifecycle of a symbol in the
library.

See docs/DesignDocs/AvailabilityMarkup.rst for more information.

Eric Fiselier b18fd9654f Fix various issues in std::any and the related tests. 
* Fix self-swap. Patch from Casey Carter.

* Remove workarounds and tests for types with deleted move constructors. This
  was originally added as part of a LWG proposed resolution that has since
  changed.

* Re-apply most recent PR for LWG 2769.

* Re-apply most recent PR for LWG 2754. Specifically fix the SFINAE checks to
  use the decayed type.

* Fix tests to allow moved-from std::any's to have a non-empty state. This is
  the behavior of MSVC's std::any.

* Various whitespace and test fixes.

Eric Fiselier 324506b9f3 [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.
