PR38682 added a test to check for a race condition in std::future.
Part of the fix is part of the dylib, but there is no released version
of mac OS X that ships a dylib containing the fix. Hence, this test can
(and sometimes does) when testing on OS X. This commit marks the test
as unsupported to avoid spurious failures.

Debian build bots are running Clang 4, which apparently does not support
the "deprecated" attribute properly. Clang pretends to support the attribute,
but the attribute doesn't do anything.
(live example: https://wandbox.org/permlink/0De69aXns0t1D59r)
On a separate note, I'm not sure I understand why we're even running the
libc++ tests under Clang-4. Is this a configuration we support? I can
understand that libc++ should _build_ with Clang 4, but it's not clear
to me that new libc++ headers should be usable under older compilers
like that.

Summary:
These deprecation warnings are opt-in: they are only enabled when the
_LIBCXX_DEPRECATION_WARNINGS macro is defined, which is not the case
by default. Note that this is a first step in the right direction, but
I wasn't able to get an exhaustive list of all deprecated components
per standard, so there's certainly stuff that's missing. The list of
components this commit marks as deprecated is:
in C++11:
- auto_ptr, auto_ptr_ref
- binder1st, binder2nd, bind1st(), bind2nd()
- pointer_to_unary_function, pointer_to_binary_function, ptr_fun()
- mem_fun_t, mem_fun1_t, const_mem_fun_t, const_mem_fun1_t, mem_fun()
- mem_fun_ref_t, mem_fun1_ref_t, const_mem_fun_ref_t, const_mem_fun1_ref_t, mem_fun_ref()
in C++14:
- random_shuffle()
in C++17:
- unary_negate, binary_negate, not1(), not2()

One of the SIMD tests attempted to left shift a value by 42, which
is UB when the left hand side is a 32 bit integer type.
This patch adjusts the test to use the value 4 instead of 42.

type.
Libc++ correctly asserts that a set of visitors for a variant all
return the same type. However, we use the visitation machinary to
perform relational operations. This causes a static assertion when
some of the alternatives relops return a UDT which is implicitly
convertible to bool instead of 'bool' exactly.

This commit fixes a regression introduced in r316095, where we don't match
inverted character classes when there's no negated characrers in the []'s.

These algorithms require a ForwardIterator or better. Ensure
we diagnose the contract violation at compile time instead of
of silently doing the wrong thing.
Further algorithms will be audited in upcoming patches.

Summary:
When a seed sequence would lead to having no non-zero significant bits
in the initial state of a `mersenne_twister_engine`, the fallback is to
flip the most significant bit of the first value that appears in the
textual representation of the initial state.
rand.eng.mers describes this as setting the value to be 2 to the power
of one less than w; the previous value encoded in the implementation,
namely one less than "2 to the power of w", is replaced by the correct
value in this patch.

Summary:
Since r338934, Clang emits an error when aligned allocation functions are
used in conjunction with a system libc++ dylib that does not support those
functions. This causes some tests to fail when testing against older libc++
dylibs. This commit marks those tests as UNSUPPORTED, and also documents the
various reasons for the tests being unsupported.

Summary:
These #includes are quite important, since otherwise any
#if TEST_STD_VER > 14 && defined(TEST_HAS_C11_FEATURES)
checks are always false, and so we don't actually test for C11 support
in the standard library.

I'm not sure if libcxx is asserting UTF-8 here; but on Windows the full char value is always passed through in its entirety, since the default codepage is something like Windows-1252. The replacement character is only used for non-chars there; and that should be a more portable test everywhere.
(Still pending review at https://reviews.llvm.org/D47395 which has been open since may; will ask for forgiveness rather than permission :) )

Summary:
Major QoI considerations:
- The facility is backported to C++14, same as libstdc++.
- Efforts have been made to minimize the header dependencies.
- The design is friendly to the uses of MSVC intrinsics (`__emulu`, `_umul128`, `_BitScanForward`, `_BitScanForward64`) but not implemented; future contributions are welcome.
Thanks to Milo Yip for contributing the implementation of `__u64toa` and `__u32toa`.

This commit adds a node handle type, (located in __node_handle), and adds
extract() and insert() members to all map and set types, as well as their
implementations in __tree and __hash_table.
The second half of this feature is adding merge() members, which splice nodes
in bulk from one container into another. This will be committed in a follow-up.

Summary:
This patch adds a new macro _LIBCPP_HAS_NO_VECTOR_EXTENSION for detecting
whether a vector extension (\_\_attribute\_\_((vector_size(num_bytes)))) is
available.
On the top of that, this patch implements the following API:
* all constructors
* operator[]
* copy_from
* copy_to
It also defines simd_abi::native to use vector extension, if available.
In GCC and Clang, certain values with vector extension are passed by registers,
instead of memory.
Based on D41148.
