Summary:
This patch ports libc++ LIT test cases for money formats to AIX. On AIX, the money format of locale zh_CN.UTF-8 is the similar to that of en_US.UTF-8, i.e., sign, symbol, none, value.

Since those features are general properties of the environment, it makes
sense to use them from libc++abi too, and so the name libcpp-has-no-xxx

[libcxx] Reject month 0 in get_date/__get_month
This fixes#47663.
Months in dates should be >= 1 and <= 12.
We parse up to two digits then minus one, because
we want to store this as "months since January"
(0-11).
However we didn't check that the result of that
was not -1. For example if you had (MM/DD/YYYY)
00/21/2022.
Added tests for:
* Failing if month is 0
* Failing if month is 13
* Allowing a leading zero in month e.g. "01"
Note that libc++ and libstdc++ return different
values on parsing failure, and MSVC STL returns
end of stream instead.
Handle the first two by checking for defines, MSVC STL
expects these tests to fail for other reasons already:
https://github.com/microsoft/STL/blob/main/tests/libcxx/expected_results.txt#L372
so not handling that case here.

This change is done to see whether all platforms have a CI with the

This wires in the locale in the tests and uses it in one test. This is

On Windows, like on macOS and FreeBSD, widening char(-5) in the
"C" locale succeeds and produces L'\u00fb'.
Switch widen_many to test \xfb instead of \x85; the mingw
version of btowc widens \x85 in the "C" locale into
\u2026 (which is the corresponding character according to the
Windows-1252 codepage), while Microsoft CRT's btowc widens it
into \u0085 (just like macOS and FreeBSD). Switch this to test \xfb
which is the character tested by the widen_1 test (as `char(-5)`),
which gets handled the same by all Windows implementations of btowc.

Those older versions used a different monetary decimal separator.
To avoid unnecessary churn to support that, just XFAIL the test

On Windows, constants like F::alpha and F::print are bitmasks
consisting of multiple bits (e.g. F::alpha consisting of both the
bits F::upper and F::lower). In such a case, we can't check that
all the bits from all the expected constants are set. Instead,
check that (p[i] & mask) != 0 returns the expected value.

AIX print -0.0 , inf, nan differently, which are causing the test
failures. We are OK for most other tests.
This patch remove the tests related these limitations conditionally on AIX,
so that we can enable the other tests to avoid losing test coverage.
The general direction is:
```
if strings don't differ between environments, keep the string literal "INF" and the padding, instead of folding them into variables.
```

Previously, this test snippet would report incorrect information:
F::mask m;
std::wstring in(L"\u00DA"); // LATIN CAPITAL LETTER U WITH ACUTE
f.is(in.data(), in.data() + 1, &m);
// m & F::lower would be set
The single-character version of the `is` function wasn't
affected by this issue though.
Define `_LIBCPP_CTYPE_MASK_IS_COMPOSITE_ALPHA` for Windows,
as the `alpha` / `_ALPHA` constant is a mask consisting of
multiple bits set, which avoids setting `alpha` whenver any
of the bits is set, in the `do_is` implementation.
On Windows, with the "C" locale, wchars are classified according
to their Unicode interpretation, just as in the en_US.UTF-8 locale on
all platforms.
Due to the differing classification of some characters, the
`scan_is` and `scan_not` tests are quite annoying to fix, thus just
ifdef out some of the tests for the "C" locale there - the code gets
tested with the more standard en_US.UTF-8 locale anyway.

Note, reducing ios.width() in put_long_double instead of using variable
padding, when using a variable width symbol. Some of those tests didn't
actually trigger any padding in the existing form, with a longer
currency symbol; reduce the width so there's no actual padding with the
slightly shorter currency symbol either.
The tests for the international currency symbol use the same amount of
padding on all platforms, so they still exercise the padding properly.

The old expected behaviour was specific to Apple platforms,

AIX's system header provides these C++ overloads for compatibility with
older XL C++ implementations, but they can be disabled by defining
__LIBC_NO_CPP_MATH_OVERLOADS__ since AIX 7.2 TL 5 SP 3.
Since D109078 landed clang will define this macro when using libc++ on
AIX and we already run the lit tests with it too. This change will
enable the overloads in libc++'s math.h and we'll continue to require
the compiler to define the macro going forward.

These tests are hit hard by a bug that is fixed in a newer version
of UCRT. Add a test for the specific bug, and XFAIL the tests if
that bug is present (as it is in CI).
Split out hex formatting of floats to separate test files, that
are excluded with `XFAIL: msvc`. (Based on reading the C standard for
printf formatting, it seems like this isn't necessarily a proper bug
in printf, but just a case of differing optional behaviour.)

International currency symbols (like USD, EUR) are returned with a
trailing space, like "USD ", on previously supported Unix platforms.
On Windows, the locales return them without a trailing space.
Also adjust the test for expecting a different unicode sequence for
the national currency symbol for ru_RU.UTF-8 and zh_CN.UTF-8.
Differential Revision: https://reviews.llvm.org/D120547
The zh_CN.UTF-8 locale on Glibc has got `n_sign_posn == 4` (which means
having the negative sign just after the currency symbol), but has
`int_n_sign_posn == 1` (which means before the string).
On Windows, there's no separate `int_n_sign_posn` field, so the same
`n_sign_posn` (which is 4 there too) is used for international currency
formatting too. This makes the ordering for the international case on
Windows be the same as for the national one right above it.
On Apple platforms, the fr_FR.UTF-8 locale has got `n_sign_posn == 2`
but `p_sign_posn == 1`, giving a different order for the French locale
for the negative format.
On Apple platforms for the zh_CN.UTF-8 locale, both `n_sign_posn` and
`int_n_sign_posn` are 4, but `p_sign_posn` and `int_p_sign_posn` are 1.

According to POSIX.1 (and Glibc docs, and Microsoft docs), the wctob
function returns EOF on error, not WEOF. (And wctob_l should consequently
do the same.)
The previous misconception about what this function returns on errors
seems to stem from incorrect documentation in macOS, stemming from BSD
docs with the same issue. The corresponding documentation bug in FreeBSD
was fixed in 2012 in
945aab9099,
but it hasn't been fixed for macOS yet.
The issue seems to only be a documentation issue; the implementation
on macOS actually does use EOF, not WEOF:
https://opensource.apple.com/source/Libc/Libc-1439.40.11/locale/FreeBSD/wctob.c.auto.html
On most Unices, EOF and WEOF are the same value, but on Windows,
EOF is -1, while WEOF is (unsigned short)0xFFFF. By fixing this,
two tests start passing on Windows.

On Windows, the en_US.UTF-8 locale returns `n_sign_posn == 0`, which

This fixes issue #45084 (https://llvm.org/PR45739).

Both of these test files are
`XFAIL: netbsd || linux || LIBCXX-WINDOWS-FIXME`, and then have some of
their test cases commented out when `__APPLE__`. This patch comments-in
those test cases and adjusts them all to work on Apple, while leaving the
test `XFAIL`ed on NetBSD, Linux, and 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.

Expect the same NAN formatting on Windows as on Glibc. (Both MSVC and
MinGW produce the same formatting there.)
The hex float formatting tests pass on MinGW, so opt in to those tests.
Document exactly what issues are remaining in Clang-cl/MSVC
configurations. (It's easily possible to make the tests pass there too,
but it requires a whole lot of small-scope ifndefs in the test file;
around 60 ifdefs in total for those both test files. Those could
be avoided if the CI environment could run with a newer version
of UCRT, but that's nontrivial to fix right away.)

Glibc adds a +-sign for NaN-values when showpos fmtflags are set.
