Louis Dionne b8cb1dc9ea [libc++] Make <ranges> non-experimental
When we ship LLVM 16, <ranges> won't be considered experimental anymore.
We might as well do this sooner rather than later.

[libc++] Replace _LIBCPP_HAS_NO_CONCEPTS with _LIBCPP_STD_VER > 17. NFCI.
All supported compilers that support C++20 now support concepts. So, remove
`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in
the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

Arthur O'Dwyer 53406fb691 [libc++] Guard much of std::ranges under _LIBCPP_HAS_NO_INCOMPLETE_RANGES.
The logic here is that we are disabling *only* things in `std::ranges::`.
Everything in `std::` is permitted, including `default_sentinel`, `contiguous_iterator`,
`common_iterator`, `projected`, `swappable`, and so on. Then, we include
anything from `std::ranges::` that is required in order to make those things
work: `ranges::swap`, `ranges::swap_ranges`, `input_range`, `ranges::begin`,
`ranges::iter_move`, and so on. But then that's all. Everything else (including
notably all of the "views" and the `std::views` namespace itself) is still
locked up behind `_LIBCPP_HAS_NO_INCOMPLETE_RANGES`.

Arthur O'Dwyer 8507383631 [libc++] [ranges] ADL-proof the [range.access] CPOs.
For example, `std::ranges::range<Holder<Incomplete>*>` should be
well-formed false, not a hard error at compile time.

Louis Dionne 4a47ac7d51 [libc++] Remove incorrect default constructor in cpp17_input_iterator
AFAICT, Cpp17InputIterators are not required to be default constructible,
since that requirement is added in Cpp17ForwardIterator. Hence, our
archetype for Cpp17InputIterator should not be default constructible.
Removing that constructor has a ripple effect on a couple of tests that
were making incorrect assumptions. Notably:

- Some tests were using cpp17_input_iterator as a sentinel for itself.
  That is not valid, because a cpp17_input_iterator is not semiregular
  anymore after the change (and hence it doesn't satisfy sentinel_for).

- Some tests were using a stride-counted cpp17_input_iterator as the
  sentinel for a range. This doesn't work anymore because of the problem
  above, so these tests were changed not to check stride counts for
  input iterators.

- Some tests were default constructing cpp17_input_iterator when a simple
  alternative was available -- those have been changed to use that alternative.

Louis Dionne 770602cfa0 [libc++] Various cleanups in the ranges tests
- Rename test files to follow conventions better
- Split constructor tests that were in a single file
- Add missing tests for take_view and transform_view's default constructors
- Add missing tests for transform_view's view/function constructor
- Fix include guards
- Mark some tests as being specific to libc++

Louis Dionne 6900df37d2 [libc++] Remove Lit annotations for unsupported GCC versions from the test suite
Since we officially don't support several older compilers now, we can
drop a lot of the markup in the test suite. This helps keep the test
suite simple and makes sure that UNSUPPORTED annotations don't rot.

This is the first patch of a series that will remove annotations for
compilers that are now unsupported.

Mark de Wever 71909de374 [libc++] Disable incomplete library features.
Adds a new CMake option to disable the usage of incomplete headers.
These incomplete headers are not guaranteed to be ABI stable. This
option is intended to be used by vendors so they can avoid their users
from code that's not ready for production usage.

The option is enabled by default.

Christopher Di Bella d8fad66149 [libcxx][ranges] adds concept `sized_range` and cleans up `ranges::size`
* 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'.
