Summary:
Tests marked with the flaky attribute ("FLAKY_TEST.")
can still report false positives in local tests and on the
NetBSD buildbot.
Additionally a number of tests (probably all threaded
ones) unmarked with the flaky attribute is flaky on
NetBSD.
An ideal solution on the libcxx side would be to raise
max retries for NetBSD and mark failing tests with
the flaky flag, however this adds more maintenance
burden and constant monitoring of flaky tests.
Reduce the work and handle flaky tests as more flaky
on NetBSD and allow flakiness of other tests on
NetBSD.

Summary:
We already have the negation of that as _LIBCPP_HAS_NONUNIQUE_TYPEINFO.
Having both defined is confusing, since only one of them is used.

This patch implements path::compare according to the current spec. The
only observable change is the ordering of "/foo" and "foo", which orders
the two paths based on having or not having a root directory (instead
of lexically comparing "/" to "foo").

Some tests assume that iteration through an unordered multimap elements
will return them in the same order as at the container creation. This
assumption is not true since the container is unordered, so that no
specific order of elements is ever guaranteed for such container. This
patch introduces checks verifying that any iteration will return elements
exactly from a set of valid values and without repetition, but in no
particular order.

Makes libc++ behavior consistent between C++03 and C++11.
Can use `decltype` in C++03 because `include/__config` defines a macro when
`decltype` is not available.

That test doesn't fail anymore since r349378, since the assertions that
r349378 removed must have been bugs in the dylib at some point.

This test was initially marked as XFAIL using `XFAIL: macosx10.YY`, and
was then moved to `UNSUPPORTED: macosx10.YY`. The intent is to mark the
test as XFAILing when a deployment target older than macosx10.14 is used,
and the right way to do this is `XFAIL: availability=macosx10.YY`.

Add a target_info definition for NetBSD. The definition is based
on the one used by FreeBSD, with libcxxrt replaced by libc++abi,
and using llvm-libunwind since we need to use its unwinder
implementation to build anyway.
Additionally, XFAIL the 30 tests that fail because of non-implemented
locale features. According to the manual, NetBSD implements only
LC_CTYPE part of locale handling. However, there is a locale database
in the system and locale specifications are validated against it,
so it makes sense to list the common locales as supported.
If I'm counting correctly, this change enables additional 43 passing
tests.

Remove the two test cases for \xDA and \xFA with UTF-8 locale, as both
characters alone are invalid in UTF-8 (short sequences). Upon removing
them, the test passes on Linux again (and also on NetBSD, after adding
appropriate locale configuration).

Replace the mknod() call with socket() + bind() for creating unix
sockets. The mknod() method is not portable and does not work
on NetBSD while binding the socket should work on all systems supporting
unix sockets.

Explicitly disable the -Wformat-zero-length diagnostic when running
ctime tests, since one of the test cases passes zero-length format
string to strftime(). When strftime() is appropriately decorated
with __attribute__(format, ...), this caused the test to fail because
of this warning (e.g. on NetBSD).

Otherwise, even specifying a runtime root different from the library
we're linking against won't work -- the library we're linking against
is always used. This is undesirable if we try testing something like
linking against a recent libc++.dylib but running the tests against an
older version (the back-deployment use case).

Fixes a bug where functions would get exported when building with
-fvisibility=hidden and defining _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS. No
visibility annotations should be added in this case.
The new logic for _LIBCPP_EXPORTED_FROM_ABI matches that of the other visibility
annotations around it.

Also, add tests making sure that vector and deque both catch the problem
when assertions are enabled. Otherwise, deque would segfault and vector

Other standard libraries don't implement availability markup, so it doesn't

This is part of an ongoing cleanup of the LIT test suite, where I'm
trying to reduce the number of configuration options. In this case,
the original intent seemed to be running the test suite with libstdc++,
but this is now supported by specifying cxx_stdlib_under_test=libstdc++.
