The macro that opts out of `std::ranges::` functionality is called
`_LIBCPP_HAS_NO_INCOMPLETE_RANGES`, and is unrelated to this macro
which is specifically about _compiler_ support for the _syntax_.
The only non-mechanical diff here is in `<__config>`.

For example, `std::ranges::range<Holder<Incomplete>*>` should be
well-formed false, not a hard error at compile time.

Clang is gaining `auto(x)` support in D113393; sadly there
seems to be no feature-test macro for it. Zhihao is opening
a core issue for that macro.
Use `_LIBCPP_AUTO_CAST` where C++20 specifies we should use `auto(x)`;
stop using `__decay_copy(x)` in those places.
In fact, remove `__decay_copy` entirely. As of C++20, it's purely
a paper specification tool signifying "Return just `x`, but it was
perfect-forwarded, so we understand you're going to have to call
its move-constructor sometimes." I believe there's no reason we'd
ever need to do its operation explicitly in code.
This heisenbugs away a test failure on MinGW; see D112214.

These are specced as `inline constexpr auto`; the extra `const`
isn't doing anything except being inconsistent with the other CPOs.
Now all the implemented CPOs can be detected by
git grep 'inline constexpr auto.*fn' ../libcxx/include/
and I think that's beautiful.
We don't use double underscores for private header names when they are
in a subdirectory with double underscores already.

We've been forgetting to add those to most of the <ranges> review.
To avoid forgetting in the future, I added an item in the pre-commit
checklist.

Moves:
* `std::move`, `std::forward`, `std::declval`, and `std::swap` into
`__utility/${FUNCTION_NAME}`.
* `std::swap_ranges` and `std::iter_swap` into
`__algorithm/${FUNCTION_NAME}`

This has been broken out of D104170 since it should be merged whether or
not we go ahead with the module map changes.

This commit alphabetizes all includes in libcxx. This is a NFC.
This can also serve as a pseudo "announcement" for how we should order these headers going forward (note: double underscores go before other headers).

* adds `sized_range` and conformance tests
* moves `disable_sized_range` into namespace `std::ranges`
* removes explicit type parameter
Implements part of P0896 'The One Ranges Proposal'.

Both `<type_traits>` and `<charconv>` implemented this function with
different names and a slightly different behavior. This removes the
version in `<charconv>` and improves the version in `<typetraits>`.
- The code can be used again in C++11.
- The original claimed C++14 support, but `[[nodiscard]]` is not
available in C++14.
- Adds `_LIBCPP_INLINE_VISIBILITY`.
