Louis Dionne 99ae458231 [libc++] Add CI without experimental features and don't exclude span from the tests
There is no reason for the parts of std::span that don't depend on ranges
to be disabled when ranges aren't provided. Also, to make sure the
"no-experimental-stuff" configuration is tested, add a CI job for it.

[libc++] Implement P1394r4 for span: range constructor
Implement https://wg21.link/p1394 which allows span to be constructible
from any contiguous forwarding-range that has a compatible element type.

Arthur O'Dwyer d4b59a05fc [libc++] Remove "// -*- C++ -*-" comments from all .cpp files. NFCI.
Even if these comments have a benefit in .h files (for editors that
care about language but can't be configured to treat .h as C++ code),
they certainly have no benefit for files with the .cpp extension.

Discussed in D110794.

Christopher Di Bella 6cb05ca392 [libcxx][modularisation] adds several headers to the module map
* <__algorithm/iter_swap.h>
* <__algorithm/swap_ranges.h>
* <__functional/is_transparent.h>
* <__memory/uses_allocator.h>
* <__ranges/drop_view.h>
* <__ranges/transform_view.h>
* <shared_mutex>
* <span>

Also updates header inclusions that were affected.

**NOTE:** This is a proper subset of D105932. Since the content has
already been LGTM'd, I intend to merge this patch without review,
pending green CI. I decided it would be better to move these changes
into their own commit since the former patch has undergone further
changes and will need yet another light review. In the event any of
that gets rolled back (for whatever reason), the changes in this patch
won't be affected.

Louis Dionne 31cbe0f240 [libc++] Remove the c++98 Lit feature from the test suite
C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.

This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.

Louis Dionne b5abd50f06 [libc++] span: Guard against overflow in span::subspan
The calculation _Offset + _Count <= size() may overflow, so use
_Count <= size() - _Offset instead. Note that this is safe due to
the previous constraint that _Offset <= size().
