Martin Storsjö b5e228fc00 [libcxx] [test] Fix the temp_directory_path test for windows
Check a different set of env vars, don't check the exact value
of the fallback path. (GetTempPath falls back to returning the Windows
folder if nothing better is available in env vars.)

The test still fails one check on windows (due to relying on perms::none),
which will be addressed separately.

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
input/output often goes through utf8 inbetween, which causes extra
allocations.

MS STL also fails a number of strict allocation checks, so this
shouldn't be a standards compliance issue.

Martin Storsjö e69c65d5c4 [libcxx] Test accessing a directory on windows that gives "access denied" errors
Fix handling of skip_permission_denied on windows; after converting
the return value of GetLastError() to a standard error_code, ec.value()
is in the standard errc range, not a native windows error code. This
was missed in 156180727d.

The directory "C:\System Volume Information" does seem to exist and
have these properties on most relevant contempory setups.

Martin Storsjö 49173ca4db [libcxx] Avoid intermediate string objects for substrings in windows operator/=
Check that appends with a path object doesn't do allocations, even

Martin Storsjö e23317c9da [libcxx] [test] Adjust separator form in fs.op.absolute for libc++ on windows
This test was previously tweaked in
321f696920 to match the output of
of MS STL (except that the MS STL fails on the testcase with an
empty path).

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.

In file_type_obs.pass.cpp, we can't inline the calls to

because the lambda removes the referenced file, and the hardlink
must be created while the earlier test file exists.

Louis Dionne a0839b14df [libc++] Fix tuple assignment from types derived from a tuple-like
The implementation of tuple's constructors and assignment operators
currently diverges from the way the Standard specifies them, which leads
to subtle cases where the behavior is not as specified. In particular, a
class derived from a tuple-like type (e.g. pair) can't be assigned to a
tuple with corresponding members, when it should. This commit re-implements
the assignment operators (BUT NOT THE CONSTRUCTORS) in a way much closer
to the specification to get rid of this bug. Most of the tests have been
stolen from Eric's patch https://reviews.llvm.org/D27606.

As a fly-by improvement, tests for noexcept correctness have been added
to all overloads of operator=. We should tackle the same issue for the
tuple constructors in a future patch - I'm just trying to make progress
on fixing this long-standing bug.
