Arthur O'Dwyer 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.

Mark de Wever cef9978027 [libc++][doc] Use issue labels.
During the review of D111166 I had a private discussion with @ldionne to
avoid the duplication of the C++2b issues in the Ranges and Format
status pages. The main reason for duplicating them is to make it easier to
find them. The title of the paper may not always make it clear to which
project the paper belongs.

This commit removes all LWG-issues from the Ranges and Format status page
and adds labels for these issue in the C++20/C++23 issues list.

A quick scan revealed there are some issues that are missing a label since
they weren't on the ranges issue list. These can be labelled in a separate
commit. In that commit I'll also look for issues for the spaceship operator
and chrono.

[libc++] LWG3480: make (recursive_)directory_iterator C++20 ranges
Implement LWG3480 which enables `directory_iterator` and
`recursive_directory_iterator` to be both a `borrowed_range` and a
`view`.

Arthur O'Dwyer 3894a8a476 [libc++] Implement the resolutions of LWG3506 and LWG3522.
Implement the changes in all language modes.

LWG3506 "Missing allocator-extended constructors for priority_queue"
makes the following changes:
- New allocator-extended constructors for priority_queue.
- New deduction guides targeting those constructors.

LWG3522: "Missing requirement on InputIterator template parameter
for priority_queue constructors". The iterator parameter should be
constrained to actually be an iterator type. `priority_queue{1,2}`
should be SFINAE-friendly ill-formed.

Also, do a drive-by fix in the allocator-extended move constructor:
there's no need to do a `make_heap` after moving from `__q.c` into
our own `c`, because that container was already heapified when it
was part of `__q`. [priqueue.cons.alloc] actually specifies the
behavior and does *not* mention calling `make_heap`. I think this
was just a copy-paste thinko. It dates back to the initial import
of libc++.

Louis Dionne cf005c4c50 [libc++] NFC: Move the status docs to their own subdirectory
This cleans up the libcxx/doc directory quite a bit and will avoid the
proliferation of status files in that directory as new standards are voted.
