Popen.communicate() method in Python 2 returns a pair of strings, and in
Python 3 it returns a pair of byte-like objects unless universal_newlines
is set to True. This led to an error when using Python 3. With this patch,
merge_archives.py works fine with Python 3.
Thanks to Sergej Jaskiewicz for the patch.

The build should generally be quiet if there are no errors,
and this script has been around long enough that we can remove
the log output. If we ever need to debug something with this script,
we can put back the logging then.

If the compiler is (for example) AppleClang 10.0.1, we would previously
populate the following lit features:
apple-clang
apple-clang-10
apple-clang-10.0
This patch additionally populates a feature called 'apple-clang-10.0.1',
which allows more precise enabling/disabling of tests.

Summary:
Quote the value of environment variables when passing them to the SSH
client in SSHExecutor in libc++'s lit utilities. Without the quotes,
an environment variable like FOO="buzz bar" gets passed incorrectly
like this, ssh env FOO=buzz bar, which causes bar to be treated as a
command to run, not part of the environment variable value.
We ran into this when using SSHExecutor to do bringup of our CUDA
libcu++ port on an embedded aarch64 system.

This commit adds a __pstl_config_site header that contains the value of
macros specified at CMake configuration time. It works similarly to
libc++'s __config_site header, except we always include it as a separate
file instead of concatenating it to the main configuration header.
It is necessary to thread the includes for that header into libc++'s
lit configuration, otherwise we'd be requiring an installation step
prior to running the test suite.

Summary:
This commit allows specifying LIBCXX_ENABLE_PARALLEL_ALGORITHMS when
configuring libc++ in CMake. When that option is enabled, libc++ will
assume that the PSTL can be found somewhere on the CMake module path,
and it will provide the C++17 parallel algorithms based on the PSTL
(that is assumed to be available).
The commit also adds support for running the PSTL tests as part of
the libc++ test suite.
The first attempt to commit this failed because it exposed a bug in the
tests for modules. Now that this has been fixed, it should be safe to
commit this.

There are a handful of standard library types that are intended
to support CTAD but don't need any explicit deduction guides to
do so.
This patch adds a dummy deduction guide to those types to suppress
-Wctad-maybe-unsupported (which gets emitted in user code).

The test configuration contained a bug where we only raised
the __config_site commands to the command line if modules were
enabled for all of the libc++ tests. However there are special
modules-only tests, and these tests weren't getting the correct
defines.
This patch corrects that issue.

Summary:
On AIX psutil can run into problems with permissions to read the process
tree, which causes problems for python timeout tests which need to kill off
a test and it's children.
This patch adds a workaround by invoking shell via subprocess and using a
platform specific option to ps to list all the descendant processes so we can
kill them. We add some checks so lit can tell whether timeout tests are
supported with out exposing whether we are utilizing the psutil
implementation or the alternative.

libc++'s lit configuration infers the C++ language dialect when it is
not provided by checking which -std= flags that a compiler supports.
GCC 5 and GCC 6 have a -std=c++17 flag, however, they do not have full
C++17 support. The lit configuration has hardcoded logic that removes
-std=c++1z as an option to test for GCC < 7, but not -std=c++17.
This leads to a bunch of failures when running libc++ tests with GCC 5
or GCC 6. This patch adds -std=c++17 to the list of flags that are
discarded for GCC < 7 by lit's language dialect inference.
Thanks to Bryce Adelstein Lelbach for the patch.

Use binary mode to read test files in libcxx LibcxxTestFormat class.
This ensures that tests are read correctly independently of encoding,
and therefore fixes UnicodeDecodeError when file is opened in Python 3
that defaults to pure ASCII encoding.
Technically this could be also fixed via conditionally appending
encoding argument when opening the file in Python 3. However, since
the code in question only searches for fixed ASCII substrings reading
it in binary mode is simpler and more universal.

Summary:
This provides the `std::destroying_delete_t` declaration in C++2a and after. (Even when the compiler doesn't support the language feature).
However, the feature test macro `__cpp_lib_destroying_delete` is only defined when we have both language support and C++2a.

This patch adds support for it in libc++.

Summary:
Ensure we re-export __cxa_throw_bad_array_new_length and
__cxa_uncaught_exceptions from libc++, since they are now
provided by libc++abi.
Doing this allows us to stop linking explicitly against libc++abi in
the libc++abi tests, since libc++ re-exports all the necessary symbols.
However, there is one caveat to that. We don't want libc++ to re-export
__cxa_uncaught_exception (the singular form), since it's only provided
for backwards compatibility. Hence, for the single test where we check
this backwards compatibility, we explicitly link against libc++abi.

We used to do it against the current system's libc++abi, which is not as
good as doing it with the libc++abi that matches the libc++ we're running
against.
Note that I made sure we were indeed picking up the provided libc++abi
by replacing it by something that doesn't work and watching it burn.

Summary:
I can't see a good reason to disallow this, even though it isn't the
standard way we build libc++ for Apple platforms.
Making this work on Apple platforms requires using different flags for
--whole-archive and removing the -D flag when running `ar` to merge
archives because that flag isn't supported by the `ar` shipped on Apple
platforms. This shouldn't be an issue since the -D option appears to be
enabled by default in GNU `ar`.
