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`.

67151d029b [libc++] [ranges] Implement P2415R2 owning_view.
"What is a view?"
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2415r2.html
https://github.com/cplusplus/draft/pull/5010/files

This was a late-breaking (Oct 2021) change to C++20.
The only thing missing from this patch is that we're supposed
to bump the feature-test macro from
    #define __cpp_lib_ranges 202106L
to
    #define __cpp_lib_ranges 202110L
but we can't do that because we don't implement all of 202106 Ranges yet.

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.

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.

8d0dfa0d57 [libcxx] Reenable ranges for clang-cl
This reverts a224bf8ec423b42eea251407e7a6cc8398a5edf4 and fixes the
underlying issue.

The underlying issue is simply that MSVC headers contains a define
like "#define __in", where __in is one macro in the MSVC Source
Code Annotation Language, defined in sal.h

Just use a different variable name than "__in"
__indirectly_readable_impl, and add "__in" to nasty_macros.h just
like the existing __out. (Also adding a couple more potentially
conflicting ones.)
