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.

Different platforms implement the wait/sleep functions in difrerent ways.
It makes sense to externalize this into the threading API.

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

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).
Fixes D29140.

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.
Fixes D29138.

Actually test what basic_string's typedefs stand for.

NotDerived and ND were completely unused.

P2 was mistakenly not being used. Yes, that's
right: -Wunused-local-typedef CAUGHT A MISTAKE! AMAZING!

Guard typedefs and static_asserts with _LIBCPP_VERSION.
test/std/containers/sequences/vector.bool/move_assign_noexcept.pass.cpp
test/std/containers/sequences/vector.bool/move_noexcept.pass.cpp
test/std/containers/sequences/vector.bool/swap_noexcept.pass.cpp
Additionally deal with conditional compilation.
test/std/containers/associative/map/map.cons/move_noexcept.pass.cpp
test/std/containers/associative/multimap/multimap.cons/move_noexcept.pass.cpp
Additionally deal with typedefs used by other typedefs.
Fixes D29135.

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.

It is my opinion that libc++ should never use `<cassert>`, including in the `dylib`.
This patch remove all uses of `assert` from within libc++ and replaces most of them with `_LIBCPP_ASSERT` instead.
Additionally this patch turn `LIBCXX_ENABLE_ASSERTIONS` off by default,
because the standard library should not be aborting user programs unless explicitly asked to.
llvm-svn: 294107
Visible definitions for basic_string::assign are sometimes emitted in
the dylib depending on the version of LLVM used to compile libc++.
This can cause the check-cxx-abilist target to fail.
This patch attempts marks the basic_string::assign templates as inline
to prevent this. That way the export list is consistent across LLVM
versions.

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.
