Arthur O'Dwyer fa6b9e4010 [libc++] Normalize all our '#pragma GCC system_header', and regression-test.
Now we'll notice if a header forgets to include this magic phrase.

Mark de Wever d7c4072fdb [libc++] Remove unneeded qualifier.
In D117811 @Quuxplusone pointed out the friend declarations don't need
to be qualified. Removing the qualification should avoid needing to add
a GCC work-around when changing _VSTD to std.

Mark de Wever ade6d0d8fa [libc++][format] Adds formatter handle.
This implements the handler according to P0645. P2418 changes the wording
in the Standard. That isn't implemented and requires changes in more
places. LWG3631 applies modifications to P2418, but is currently
unresolved.

Implements parts of:
* P0645 Text Formatting

Depends on D115989

Mark de Wever 787ccd345c [libc++][format] Adds formatter pointer.
This implements the last required formatter specialization.

Completes:
- LWG 3251 Are std::format alignment specifiers applied to string arguments?
- LWG 3340 Formatting functions should throw on argument/format string mismatch in §[format.functions]
- LWG 3540 §[format.arg] There should be no const in basic_format_arg(const T* p)

Implements parts of:
- P0645 Text Formatting

Mark de Wever dfb20d4d19 [libc++][format] Improve ABI stability.
During the review of D115991 @vitaut pointed out the enum shouldn't
depend on whether or not _LIBCPP_HAS_NO_INT128 is defined. The current
implementation lets the enum's ABI depend on this configuration option
without a good cause.

Mark de Wever 1637921134 [libc++][NFC] Move concepts to a subheader.
D103357 added some new concepts. Since the header `<concepts>` has moved
all its concepts to a separate header these new concepts feel out of
place. Move them to the appropriate header.

Mark de Wever 67794e784e [libc++][nfc] Fixes ppc64le-sanitizer build issue.

This replaces all occurrences with `__boolean`.

Mark de Wever 0922ce56f4 [libc++][format] Add __format_arg_store.
This implements the struct `__format_arg_store` and its dependencies:
* the class basic_format_arg,
* the class basic_format_args,
* the class basic_format_context,
* the function make_format_args,
* the function wmake_format_args,
* the function visit_format_arg,
* several Standard required typedefs.

The following parts will be implemented in a later patch:

* the child class `basic_format_arg::handle`,
* the function `basic_format_arg::basic_format_arg(const T* p)`.

The following extension has been implemented:
* the class basic_format_arg supports `__[u]int128_t` on platform where libc++ supports 128 bit integrals.

Implements parts of:
* P0645 Text Formatting

Completes:
* LWG3371 visit_format_arg and make_format_args are not hidden friends
* LWG3542 basic_format_arg mishandles basic_string_view with custom traits
