fbc80168bb Add <optional> header. 
This patch is largely thanks to Casey Carter @ Microsoft. He did the initial
work of porting our experimental implementation and tests over to namespace
std.

to return true for function types; ex [T = void()].

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.

a3eac518e6 [libcxx] Improve tests to use the UNSUPPORTED lit directive 
Quite a few libcxx tests seem to follow the format:
 #if _LIBCPP_STD_VER > X
   // Do test.
 #else
   // Empty test.
 #endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.

6aec0206da Fix PR27538. Remove __is_convertible specializations for array and function types. 
This patch fixes a bunch of bugs in the fallback implementation of
is_convertible, which is used by GCC. Removing the "__is_convertible"
specializations for array/function types we fallback on the SFINAE test,
which is more correct.

1e5a4a4a71 Fix or move various non-standard tests. 
This patch does the following:

* Remove <__config> includes from some container tests.
* Guards uses of std::launch::any in async tests because it's an extension.
* Move "test/std/extensions" to "test/libcxx/extensions"
* Moves various non-standard tests including those in "sequences/vector",
  "std/localization" and "utilities/meta".

8d5cbd7ce2 Add 'is_callable' and 'is_nothrow_callable' traits and cleanup INVOKE. 
The primary purpose of this patch is to add the 'is_callable' traits.
Since 'is_nothrow_callable' required making 'INVOKE' conditionally noexcept
I also took this oppertunity to implement a constexpr version of INVOKE.
This fixes 'std::experimental::apply' which required constexpr 'INVOKE support'.

This patch will be followed up with some cleanup. Primarly removing most
of "__member_function_traits" since it's no longer used by INVOKE (in C++11 at least).

e39f4b996e Fix various GCC mis-configurations for newer versions. 
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:

1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.
