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.

Summary:
Replace non-Standard "atomic_flag f(false);" with Standard "atomic_flag f;" in clear tests.
Although the value of 'f' is unspecified it shouldn't matter because these tests always call `f.test_and_set()` without checking the result, so the initial state shouldn't matter.
The test init03.pass.cpp is explicitly testing this non-Standard extension; It has been moved into the `test/libcxx` directory.

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".

Testing the concrete implementation of INVOKE means calling the implementation
specific names `__invoke` and `__invoke_constexpr`. For this reason the test
are non-standard. For this reason it's best if the tests live outside of the
`test/std` directory.

Summary:
Hi,
When creating a new thread libc++ performs at least 2 allocations. The first allocates a tuple of args and the functor that will be passed to the new thread. The second allocation is for the thread local storage needed internally by libc++. Currently the second allocation happens in the child thread, meaning that if it throws the program will terminate with an uncaught bad alloc.
The solution to this is to allocate ALL memory in the parent thread and then pass it to the child.

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).

In cases where emplace is called with two arguments and the first one
matches the key_type we can Key to check for duplicates before allocating.
This patch expands on work done by dexonsmith@apple.com.
