05761e6861 Fix a couple of warnings present in the filesystem tests.

6e9a694dce Add Filesystem TS -- Complete 
Add the completed std::experimental::filesystem implementation and tests.
The implementation supports C++11 or newer.

The TS is built as part of 'libc++experimental.a'. Users of the TS need to
manually link this library. Building and testing the TS can be disabled using
the CMake option '-DLIBCXX_ENABLE_FILESYSTEM=OFF'.

Currently 'libc++experimental.a' is not installed by default. To turn on the
installation of the library use '-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON'.

629aa5670a [libcxx] [test] In test/support/test_allocator.h, fix construct() to avoid moving immovable types. 
Summary:
In test/support/test_allocator.h, fix construct() to avoid moving immovable types.

This improves the allocator's conformance, and fixes compiler errors with MSVC's STL. The scenario is when the allocator is asked to construct an object of type X that's immovable (deleted copy/move ctors), but implicitly constructible from an argument type A. When perfectly forwarded, X can be (explicitly) constructed from A, and everything is fine. That's std::allocator's behavior, and the Standard's default when a user allocator's construct() doesn't exist. The previous implementation of construct() here mishandled this scenario. Passing A to this construct() would implicitly construct an X temporary, bound to (non-templated) T&&. Then construct() would attempt to move-construct X from that X temporary, but X is immovable, boom.

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.

a30cee2258 Make system_error::message() thread safe. Fixes PR25598. 
Summary:
system_error::message() uses `strerror` for the generic and system categories. This function is not thread safe.

The fix is to use `strerror_r`. It has been available since 2001 for GNU libc and since BSD 4.4 on FreeBSD/OS X.
On platforms with GNU libc the extended version is used which always returns a valid string, even if an error occurs.

In single-threaded builds `strerror` is still used.

68db6cdf1b Cleanup non-standard tests as reported by STL@microsoft.com. NFC. 
This patch addresses the following issues in the test suite:

1. Move "std::bad_array_length" test from std/ to libcxx/ test directory
   since the feature is not a part of the standard.

2. Rename "futures.tas" test directory to "futures.task" since that is the
   correct stable name.

3. Move tests for "packaged_task<T>::result_type" from std/ to libcxx/
   test directory since the typedef is a libc++ extension.
