Summary:
Benchmarks for std::sort, std::stable_sort, std::make_heap,
std::sort_heap, std::pop_heap and std::push_heap.
The benchmarks are run with integers and strings, and with different
sorted input.

The XFAIL started passing since we're only testing for trivial-copyability of
reference_wrapper in C++14 and above. This commit constrains the XFAIL to
gcc-4.9 with C++14 (it would also fail on C++17 and above, but those standards
are not available with GCC 4.9).

Some tests use type std::max_align_t, but don't include <cstddef> header
directly. As a result, these tests won't compile against some conformant
libraries.

Thanks to Andrey Maksimov for the patch.

A bunch of unordered containers tests call library functions but don't directly
include the corresponding header files:
- fabs() (defined in <cmath> which is not included);
- is_permutation() (defined in <algorithm> which is not included);
- next() (defined in <iterator> which is not included).
- As a result, these tests won't compile against some conformant libraries.

I also kept the original "vague" documentation that saying that users are
responsible for not breaking us. This doesn't mean anything because there's
no way they can actually enforce that unless we restrict ourselves to a
specific naming scheme, but I left the documentation because it acts as a
good warning and gives us more leeway.

This was implicitly converting [1, 3] to bool, which triggers
an MSVC warning. The test should just pass `true`, which is
simpler, has the same behavior, and avoids the warning. (This
is a library test, not a compiler test, and the conversion happens
before calling `push_back`, so passing [1, 3] isn't interesting
in any way. This resembles a previous change to stop passing
`1 == 1` in the `vector<bool>` tests.)

This patch renames the cxx-benchmark-unittests to check-cxx-benchmarks
and converts the target to use LIT in order to make the tests run faster
and provide better output.
In particular this runs each benchmark in a suite one by one, allowing
more parallelism while ensuring output isn't garbage with multiple threads.
Additionally, it adds the CMake flag '-DLIBCXX_BENCHMARK_TEST_ARGS=<list>'
to specify what options are passed when running the benchmarks.

Summary:
The result of subprocess.check_output() is bytes in python3 which we need
to convert to str(). Simplify this by using the executeCommand() helper.

This is needed when cross-compiling for a different target since
CFLAGS may contain additional flags like -resource-dir which
change the location in which compiler-rt builtins are found.

This patch adds the cxx-benchmark-unittests target so we can start
getting test coverage on the benchmarks, including building with
sanitizers. Because we're only looking for test-coverage, the benchmarks
run for the shortest time possible, and in parallel.
The target is excluded from all by default. It only
builds and runs the libcxx configurations of the benchmarks, and not
any versions built against the systems native standard library.

The usage of aligned_storage failed to pass the alignment it wanted,
which caused it to have a larger size and alignment that the
std::string's it was intended to store.
This patch manually specifies the alignment, as well as cleaning up
type alias bugs.

Summary:
P1006 adds support for constexpr in the specialization of pointer_traits
for raw pointers. This is necessary in order to use pointer_traits in
the upcoming constexpr containers. We expect P1006 to be voted into the
working draft for C++20 at the San Diego meeting.

The benchmarks currently require C++17, however Clang 3.9 doesn't
support -std=c++17 while still supporting all the C++17 features needed
to compile the benchmarks.
This patch makes the benchmark build attempt to fall back to -std=c++1z
when -std=c++17 isn't supported.

This patch adds tests to ensure that multiset/unordered_multiset's emplace
method correctly constructs the elements without any intervening
constructions.
