Martin Storsjö abe46776f3 [libcxx] [test] Fix the classic_table test on Windows
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.

Jinsong Ji 706e37c8e0 [libc++][AIX][test] Enable put_double/long_double locale tests
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.
```

Martin Storsjö 45415ef91b [libcxx] Fix the ctype `is` (pointer version) function for Windows
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.

Martin Storsjö df1e43c496 [libcxx] [test] Fix get/put long_double_ru_RU on Glibc, FreeBSD and Windows
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.

Martin Storsjö f1d0d6f70c [libcxx] [test] Fix the monetary locale pos/neg_format test for Windows and macOS
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.

Martin Storsjö 0f5d0d4e82 [libcxx] Fix the error checking for wctob_l, fixing locale narrow function on Windows
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.

Martin Storsjö 38d25aecdf [libcxx] [test] Use proper UTF-8 locales on 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.

Louis Dionne 87dd51983c [libc++] Remove support for CloudABI, which has been abandoned
Based on https://github.com/NuxiNL/cloudlibc, it appears that the CloudABI
project has been abandoned. This patch removes a bunch of CloudABI specific
logic that had been added to support that platform.

Note that some knobs like LIBCXX_ENABLE_STDIN and LIBCXX_ENABLE_STDOUT
coud be useful in their own right, however those are currently broken.
If we want to re-add such knobs in the future, we can do it like we've
done it for localization & friends so that we can officially support
that configuration.

Martin Storsjö 128b2136ec [libcxx] [test] Generalize defines for skipping allocation checks
This allows waiving the right amount of asserts on Windows and zOS.
This should supersede D107124 and D105910.
