The newer versions of ucrt have the math routines. Use the CRT version
to determine if we should include the math routines. Fixes two tests
for Windows.

CloudABI has gained the setlocale() function in the meantime, meaning
there is no longer a need to conditionalize this.

CloudABI does provide unistd.h, but doesn't define __unix__. We need to
include this header file to make hardware_concurrency work.

This recommits r294707 with additional fixes. The main difference is
libc++ now correctly builds without any ABI library.
exception.cpp is a bloody mess. It's full of confusing #ifdef branches for
each different ABI library we support, and it's getting unmaintainable.
This patch breaks down exception.cpp into multiple different header files,
roughly one per implementation. Additionally it moves the definitions of
exceptions in new.cpp into the correct implementation header.
This patch also removes an unmaintained libc++abi configuration.
This configuration may still be used by Apple internally but there
are no other possible users. If it turns out that Apple still uses
this configuration internally I will re-add it in a later commit.

This test validates that the lock_guard is declared variadically across
C++03 and C++11. Given the lack of stable ABI on Windows and the fact
that the RTTI encoding on Windows is different, XFAIL it on that target.

is needed to supress the warnings which are being treated as errors.

When running the tests on Windows with a debug build, _DEBUG must be
added to the flags prior to the -target as the forced inclusion of a
header will prevent the compile test for the flag to fail.

This covers how to build libc++ for Windows. This allows others to
replicate the MS ABI style build for libc++. It only depends on msvcrt
as it uses the Windows threading model and the Windows ABI and can serve
as an ABI compatible replacement for msvcprt.

std::chrono::nanoseconds. Add an explicit conversion to use the
operator+.

Summary:
Libcxx will define its own max_align_t when it is not available. However, the
availability checks today only check for Clang's definition and GCC's
definition. In particular, it does not check for musl's definition, which is the
same as GCC's but guarded with a different macro.

Libc++ frequently creates and uses utilities written in python.
Currently there are python modules under both libcxx/test and
libcxx/util. My goal with these changes is to consolidate them
into a single package under libcxx/utils/libcxx.

A static assertion was misfiring since it checked
is_callable<Visitor, decltype(__variant_alt<T>.value)>. However
the decltype expression doesn't capture the value category as
required. This patch applies extra braces to decltype to fix
that.

When building as part of runtimes, there is no predefined order in
which the runtimes are loaded, so the targets from other projects
might not be available. We need to rely on HAVE_<name> variables
instead in that case.

Filesystems are not required to maintain a hard link count consistent
with number of subdirectories. For example, on btrfs all directories
have nlink==1. Account for that in the test.

Recently I turned on libc++'s debug mode assertions when
CMake is configured with -DLIBCXX_ENABLE_ASSERTIONS=ON. This
change exposed assertion failures caused by bugs in filesystem.
This patch fixes those failures.
The first bug was that `PathParser` was using front()/back()
on empty string views in order to get the address of the character.
However this is UB on empty strings. Those operations now use data()
to obtain the pointer.
The second bug was that directory_iterator attempted to capture errno when it
was unset and there was an assertion to detect this.

This really should get identified properly by the compiler to convert to
a NVRO, but compress the code anyways. This makes the implementation
identical to directory_iterator.cpp

When compiled with Clang for Windows, this was emitting "enumerator value
evaluates to 4294967295, which cannot be narrowed to type 'int' [-Wc++11-narrowing]".
The test should more strenuously avoid poking this ABI deficiency (and it
already has coverage for explicitly specified underlying types).
Fixes D29140.
