Martin Storsjö f9ddb81d79 [libcxx] [test] Ifdef out tests that rely on perms::none on directories for triggering errors
On Windows, one can't use perms::none on a directory to trigger
failures to read the directory entries.

These remaining tests can't use GetWindowsInaccessibleDir() sensibly,
e.g. for tests that rely on toggling accessibility back and forth during
the test, or where the semantics of the dir provided by
GetWindowsInaccessibleDir() doesn't allow for running the ifdeffed tests
meaningfully.

Martin Storsjö a9a7498b3f [libcxx] [test] Allow C:\System Volume Information to be missing
If running in a Windows Container, there is no such directory at all.

If running from within bash on Windows Server, the directory seems to
be fully accessible. (The mechanics of this isn't fully understood, and
it doesn't seem to happen on desktop versions.)

If the directory isn't available with the expected behaviour, mark those
individual tests as unsupported. (The test as a whole is considered to
pass, but the unsupported test is mentioned in a test summary printed on
stdout.)

Martin Storsjö 695ec081a4 [libcxx] [test] Fix fs.op.proximate for windows
Simmilar to many other similar path handling tests, convert the
test reference to preferred separators, and ifdef a few test references
that use network root names.

Additionally, generalize code for trimming off the root path for
generating relative_cwd, and for skipping the root name element
in count_path_elems.

Rename one fictive path for consistency with the other test cases,
and add a bunch of more test cases for completeness.

This makes no attempt yet to look into the why/what for each of them,

Martin Storsjö 7a154c3230 [libcxx] [test] Account for differences in a trailing slash in weakly_canonical
This seems to be a documented quirk in libc++'s implementation of
weakly_canonical (in a comment in the weakly_canonical test).
Together with a difference between windows and posix regarding whether
paths can go through nonexistent dirs, this results in a difference in
a trailing slash.

Just document this as expected, and degrade the comment from fixme to
a note, as MS STL and libstdc++ behave in the same way.

Martin Storsjö f5f3a59837 [libcxx] [test] Disable some allocation checks in class.path tests on windows
On windows, the path internal representation is wchar_t, and

allocations.

MS STL also fails a number of strict allocation checks, so this

This test was previously tweaked in
321f696920 to match the output of

libc++ doesn't produce paths with all normalized separators (and the
spec doesn't mandate it to either).

Tweak the test reference to match exactly what libc++ produces. If
testing with a non-libc++ library, do a relaxed comparison that allows
the separators to differ.

Restructure code in directory_entry.obs/file_type_obs.pass.cpp
and directory_entry.obs/hard_link_count.pass.cpp to reduce the
amount of ifdeffery needed.

In file_type_obs.pass.cpp, we can't inline the calls to
env.create_* into the lambda calls (e.g. "test_path(env.create_*())"),
because the lambda removes the referenced file, and the hardlink
must be created while the earlier test file exists.

In hard_link_count.pass.cpp, move restoration of the original
directory permissions to the end of the lambda, so that new
directory entries can be created after the lambda has run once.

Louis Dionne 933518fff8 [libc++] Make LIBCXX_ENABLE_FILESYSTEM fully consistent
Previously, LIBCXX_ENABLE_FILESYSTEM controlled only whether the filesystem

setting to a first-class option like LIBCXX_ENABLE_LOCALIZATION, where
the whole library is aware of the setting and features that depend on
<filesystem> won't be provided at all. The test suite is also properly
annotated such that tests that depend on <filesystem> are disabled when
the library doesn't support it.

This is an alternative to https://llvm.org/D94824, but also an improvement
along the lines of LIBCXX_ENABLE_LOCALIZATION that I had been wanting to
make for a while.
