LWG issue 2218 relaxes a restriction on how containers can call
Alloc::construct(...) and Alloc::destroy(...). There is nothing new to test.

Summary:
Currently much of the libcxx website is duplicated between the old www/ documentation and newer Sphinx docs. This patch changes the main libc++ webpage so that it links to the new documentation where possible. This means removing numerous sections from the landing page.

Exactly what it sounds like.
I plan to commit this in a couple of days assuming no objections.

Summary:
This patch changes the libc++ CMake so that it adds certain target flags like '-m32' or '--gcc-toolchain' before including config-ix.cmake.
Since these flags can affect things like check_library_exists([...]) they needed to be added before the tests are performed.

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.

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.

Summary:
GLIBC recently removed the incorrect `int isinf(double)` and `int isnan(double)` overloads in C++11 and greater. This causes previously `XFAIL: linux` tests to start passing.
Since there is no longer a way to 'XFAIL' the tests I choose to simply tolerate this bug.

The existing pthread detection code in __config is pretty good for
common operating systems. It doesn't allow cmake-time choices to be
made for uncommon operating systems though.
This change adds the LIBCXX_HAS_PTHREAD_API cmake flag, which turns
into the _LIBCPP_HAS_THREAD_API_PTHREAD preprocessor define. This is
a name change from the old _LIBCPP_THREAD_API_PTHREAD. The lit tests
want __config_site.in variables to have a _LIBCPP_HAS prefix.

The various _l locale extension functions originate from very
different places. Some come from POSIX, some are BSD extensions,
and some are shared BSD and GLIBC extensions. This patch tries to
group the local extension reimplementations by source. This should
make it easier to make libcxx work with POSIX compliant C libraries
that lack these extensions.
The fallback locale functions are also useful on their own for other
lightweight platforms. Putting these fallback implementations in
support/xlocale should enable code sharing.
I have no access to a newlib system or an android system to build
and test with. I _do_ have access to a system without any of the _l
locale extensions though, and I was able to ensure that the new
__posix_l_fallback.h and __strtonum_fallback.h didn't have any massive
problems.

This patch implements the C++11 version of declval without requiring a template
instantiation.

When you assign a shared_ptr, the deleter gets called and assigned. In this routine, the assignment happens inside a critical section, which could (potentially) lead to a deadlock, if the deleter did something wonky. Now we swap the old value with an (empty) temporary shared_ptr, and then let the temporary delete the old value when it goes out of scope (after the lock has been released). This should fix PR#27724. Thanks to Hans Boehm for the bug report and the suggested fix.

This option is geared towards shared library builds and causes static
library builds to fail if not explicitly disabled.

Thanks rgoodfel@isi.edu for the catch.

Summary:
Currently libc++experimental builds with C++11. This patch changes that to C++14 when supported by the compiler. Although nothing currently requires C++14 the upcoming <experimental/memory_resource> implementation would benefit from it. [1]
Note that libc++.so continues to build with C++11 and is unaffected by this change.
[1] <experimental/memory_resource> provides global resources which must exist for the entire lifetime of the program. In order to ensure that a global resource can be used during program termination there destructors must never be invoked. The only way to do this, while also allowing "constant initialization", is to use a C++14 union.
