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.

When running the test under clang-cl, we do not report `__GNUC__`, which
is needed to supress the warnings which are being treated as errors.

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.

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.

In addition to the PR for LWG 2773 this patch also ensures
that each of std::ignores constructors or assignment operators
are constexpr.

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).

libcxx's tests use various C Standard Library functions that have been
marked by MSVC's CRT as deprecated by Microsoft (not by ISO).
libcxx's usage is cromulent (just checking with decltype to see if the functions
are being dragged in by various headers as required by the Standard), so
defining _CRT_SECURE_NO_WARNINGS will silence the warnings in a targeted manner.
This needs to be defined before including any CRT headers.
Also, make this file prettier.

N4100 states that an error shall be reported if
`!exists(p) || !is_directory(p)`. We were missing the first half of the
conditional. Invert the error and normal code paths to make the code
easier to follow.

Summary:
num_put::put uses %p for pointer types, but the exact format of %p is
implementation defined behavior for the C library. Compare output to
snprintf for portability.

Pending LIT changes are about to remove the REQUIRES-ANY keyword
in place of supporting boolean && and || within "REQUIRES". This
patch prepares libc++ for that change so that when applied
the bots don't lose their mind.

Summary:
Exactly what the title says.
This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it.
See http://wg21.link/P0513R0 for more info.
If there are no comments in the next couple of days I'll commit this
