Martin Storsjö 38d25aecdf [libcxx] [test] Use proper UTF-8 locales on Windows
Since Windows 10 version 1803 (10.0.17134.0) (or Windows Server 2019),
the Windows Universal C Runtime (UCRT) actually does support UTF-8
locales - they're available e.g. via the same names as commonly on Unices,
e.g. "en_US.UTF-8".

The UTF-8 locale support unfortunately has a bug which breaks a couple
tests that were passing previously. That bug is fixed in the very
latest version of the UCRT (in UCRT 10.0.20348.0, available in Windows
11 or Windows Server 2022), so it will get resolved at some point
eventually, provided that the CI environment does get upgraded to a
newer version of Windows Server.

While the net number of xfailed/passing tests in this patch is a loss,
this does allow fixing a lot more locale tests properly for Windows
in later patches.

Intentionally not touching the ISO-8859-1/2 locales used for testing;
they're not detected and tested/used right now, and fixing that up
is another project.

Louis Dionne 1b06d2cf15 [libc++] Refactor the Apple build scripts
This patch upstreams some changes we've made internally to how we're
building the libc++ dylib on Apple platforms. The goal is still to
eventually get rid of `apple-install-libcxx.sh` entirely and have a
proper way to mirror what we do internally with just the normal CMake
configuration.

Louis Dionne f87aa19be6 [libc++] Move everything related solely to _LIBCPP_ASSERT to its own file
This is the first step towards disentangling the debug mode and assertions
in libc++. This patch doesn't make any functional change: it simply moves
_LIBCPP_ASSERT-related stuff to its own file so as to make it clear that
libc++ assertions and the debug mode are different things. Future patches
will make it possible to enable assertions without enabling the debug
mode.

This should work now that we are using a matching libunwind.dylib when

have now is to run on macOS x86_64, since that's what the old dylibs

Louis Dionne 817d897b57 [libc++] Remove _LIBCPP_ABI_UNSTABLE
Previously, _LIBCPP_ABI_UNSTABLE would be used interchangeably with
_LIBCPP_ABI_VERSION >= 2. This was confusing and creating unnecessary
complexity.

This patch removes _LIBCPP_ABI_UNSTABLE -- instead, the LIBCXX_ABI_UNSTABLE
CMake option will result in the LIBCXX_ABI_VERSION being set to '2', the
current unstable ABI. As a result, in the code, we only have _LIBCPP_ABI_VERSION
to check in order to query the current ABI version.

As a fly-by, this also defines the ABI namespace during CMake configuration
to reduce complexity in __config. I believe it was previously done this
way because we used to try to use __config_site as seldom as possible.
Now that we always ship a __config_site, it doesn't really matter and
I think being explicit about how the library is configured in the __config_site
is actually a feature.

Louis Dionne 78205faf54 [libc++][Docker] Don't actually start using a newer compiler in the CI
To ensure a smooth transition without breaking CI, we should use explicitly
versioned Clangs in the CI jobs definition instead, since that's a change
we can actually test in the CI.

So instead of bumping the compiler version from the Docker image, use
the same version as before by default, and we can bump it from the CI
job definition once all the nodes are running the new image.

Alex Richardson 89103bd2f0 [libc++] Fix GDB pretty printers when GDB uses Python 2.7
The gdb_pretty_printer_test.sh fails if GDB was built against Python 2.7
since Python 2 expects iterators to have a next() method rather than
using __next__. To make the pretty printers work with both Python 2 and 3
we can simply set next to __next__ in the iterator classes.

Python 2.7 support was removed in f46f93b478,
so this partially reverts that commit. While Python 2.7 is EOL, it
appears there are still many GDB installations that are linked against
Python 2.7, so we may want to keep this tiny amount of compat code
around for a while longer.

Without this commit the tests fails with errors such as:
```
GDB printed:
   u"std::tuple containingTypeError: iter() returned non-iterator of type '_Children'\n"
Value should match:
   u'std::tuple containing = {[1] = 2, [2] = 3, [3] = 4}'

Louis Dionne 4afa9c1726 [libc++] Persistently cache memoized operations during Lit configuration
When invoking Lit repeatedly, we perform all the configuration checks
over and over again, which takes a lot of time. This patch allows caching
the result of configuration checks persistently across Lit invocations to
speed this up.

In theory, this should still be functionally correct since the cache
key should contain everything that determines the output of the
configuration check. However, in cases where e.g. the compiler has
changed but is at the same path as previously, the Lit configuration
checks will be cached even though technically the cache should have
been invalidated.
