Samuel Benzaquen 37632992ef Add benchmark for std::set.
Summary:
Benchmarks for construct, find, insert and iterate, with sequential
and random ordered inputs.

It also improves the cartesian product benchmark header to allow for
runtime values to be specified in the product.

Billy Robert O'Neal III 95cf9fa213 [libcxx] [test] Don't detect Windows' UCRT with TEST_COMPILER_C1XX
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.

Billy Robert O'Neal III e04704b9a9 Repair thread-unsafe modifications of n_alive in F.pass.cpp
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.

Louis Dionne 7833b88ad8 [libcxx] Remove _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY
That macro has been defined to _LIBCPP_HIDE_FROM_ABI_AFTER_V1 for many
weeks now, so we're actually replacing uses of it for uses of
_LIBCPP_HIDE_FROM_ABI_AFTER_V1 directly.

This should not change or break anything since the two macros are
100% equivalent, unless somebody is (incorrectly!) relying on
_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY being defined.

Louis Dionne 950b8e114e [libcxx] Remove custom CMake code targeting Mac OS 10.6
libc++ has dropped support for Mac OS 10.6 for a while, and we don't
have any testers set up for that OS.

This commit puts in an error message so that people can reach out to
the libc++ maintainers in case support for 10.6 is still expected (as
opposed to silently failing in weird ways). We can completely drop
support for 10.6 and remove the error message some time in the future
when we're sure that nobody is relying on it.

Summary:
Benchmarks for construct, copy, move, swap, destroy and invoke, with 8
different input states.
For the cases that matter, it tests with and without allowing constant
value propagation from construction into the operation tested.

This also adds helper functions to generate the cartesian product of
different configurations and generate benchmarks for all of them.

Eric Fiselier 33e402ae2b Fix use of removed _LIBCPP_HAS_NO_BUILTIN_ALIGNED_OPERATOR_NEW_DELETE

Eric Fiselier 42f9868cd8 Distinguish between library and language support for aligned allocation.
There are two cases:
1. The library has all it needs to provide align_val_t and the
new/delete overloads needed to support aligned allocation.
2. The compiler has actually turned the language feature on.

There are times where libc++ needs to distinguish between the two.

This patch adds the additional macro
_LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION which denotes when case (1)
does not hold. _LIBCPP_HAS_NO_ALIGNED_ALLOCATION is defined whenever
_LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION is defined, or when the
compiler has not enabled the language feature.

Additionally this patch cleans up a number of other macros related
to detection of aligned allocation machinery.
