When some headers are not available because we removed features like
localization or threads, the compiler should not try to include these
headers when building modules. To avoid that from happening, add a
requires-declaration that is never satisfied when the configuration
in use doesn't support a header.

This reverts commit f2f0dba818a50fc17ed309823b2fdb72cb725eec.
This Docker file doesn't work on the CI. It fails to clone the checkout.
This seems like an issue with a newer glibc on an older Docker where the
clone3() call fails.
This needs further investigation before relanding.
With the new version of Git in Ubuntu Jammy (which is now what we use in
our Docker image), we need to add `/llvm` to the list of safe directories
to avoid failures.
The debug mode has been broken pretty much ever since it was shipped
because it was possible to enable the debug mode in user code without
actually enabling it in the dylib, leading to ODR violations that
caused various kinds of failures.
This commit makes the debug mode a knob that is configured when
building the library and which can't be changed afterwards. This is
less flexible for users, however it will actually work as intended
and it will allow us, in the future, to add various kinds of checks
that do not assume the same ABI as the normal library. Furthermore,
this will make the debug mode more robust, which means that vendors
might be more tempted to support it properly, which hasn't been the
case with the current debug mode.
This patch shouldn't break any user code, except folks who are building
against a library that doesn't have the debug mode enabled and who try
to enable the debug mode in their code. Such users will get a compile-time
error explaining that this configuration isn't supported anymore.
In the future, we should further increase the granularity of the debug
mode checks so that we can cherry-pick which checks to enable, like we
do for unspecified behavior randomization.

In clang-cl/MSVC environments, linking against a DLL C++ standard
library requires having dllimport attributes in the headers; this
has been used for detecting whether the tests link against a DLL,
by looking at the libc++ specific define
_LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS.
In mingw environments, thanks to slightly different code generation
and a couple linker tricks, it's possible to link against a DLL C++
standard library without dllimport attributes. Therefore, don't
rely on the libc++ specific header define for the detection.
Replace the detection with a runtime test.

Add a warning and tweak the release note to explain that the deprecation
targets libc++, libc++abi and libuwnind as well.
Also, as a fly-by, ensure that our CI runs the legacy testing configuration
for libc++, libc++abi and libunwind. This doesn't matter too much since
it's deprecated, but we might as well test it properly.

This is a variant of D116689 rebased on top of the new (proposed) ABI

For example, we used to trigger CI even for commits that touched a file
whose path contained 'cmake', even if it's not the root cmake directory.
Fix that.
This patch overhauls how we pick up the ABI library. Instead of setting
ad-hoc flags, it creates interface targets that can be linked against by
the rest of the build, which is easier to follow and extend to support
new ABI libraries.
This is intended to be a NFC change, however there are some additional
simplifications and improvements we can make in the future that would
require a slight behavior change.

On targets without unistd.h or sys/wait.h (such as bare metal targets)
any test that uses check_assertion.h will fail, so add
REQUIRES: has-unix-headers to them and autodetect whether we have
these headers or not.
These tests currently have unsupported on windows, but that's exactly
because windows doesn't have these headers so we can remove the
specific check for windows.

Adding a mingw based config is easy in the current CI environment
(where we can just choose the different target by calling
`i686-w64-mingw32-clang`), while adding a clang-cl based config would
require setting up different environment variables pointing to the
i386 library directory.
Just adding one config (DLL) instead of exhaustively testing both
(DLL and static) as very few tests would differ in practice, to keep
the CI load reasonable.

This patch changes the requirement for getting the declaration of the
assertion handler from including <__assert> to including any public
C++ header of the library. Note that C compatibility headers are
excluded because we don't implement all the C headers ourselves --
some of them are taken straight from the C library, like assert.h.
It also adds a generated test to check it. Furthermore, this new
generated test is designed in a way that will make it possible to
replace almost all the existing test-generation scripts with this
system in upcoming patches.
