Summary:
Some tests (mainly the new C++20 calendar library) fail when libc++ is
tested with '--param=std=c++98'. The failures happen because the tests
actually don't support C++98, but don't mention C++98 in the
'UNSUPPORTED:' line.
This change fixes the issue.

The test is trying to avoid saying aligned_alloc on Windows' UCRT, which does not (and can not) implement aligned_alloc. However, it's testing for c1xx, meaning clang on Windows will fail this test when using the UCRT.

In this example, the ctor of G runs in the main thread in the expression G(), and also in the copy ctor of G() in the DECAY_COPY inside std::thread. The main thread destroys the G() instance at the semicolon, and the started thread destroys the G() after it returns. Thus there is a race between the threads on the n_alive variable.
The fix is to join with the background thread before attempting to destroy the G in the main thread.

Some of the buildbot failures were masked by another error,
and this one was probably missed.

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.

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.
