Extended integral type support
------------------------------
Several platforms support types that are not specified in the Standard, such as
the 128-bit integral types ``__int128_t`` and ``__uint128_t``. As an extension,
libc++ does a best-effort attempt to support these types like other integral
types, by supporting them notably in:
* ``<bits>``
* ``<charconv>``
* ``<functional>``
* ``<type_traits>``
* ``<format>``
* ``<random>``
Additional types supported in random distributions

Extended integral type support
------------------------------
Several platforms support the 128-bit integral types ``__int128_t`` and
``__uint128_t``. When these types are present they can be used in the headers
as required by the Standard:
* ``<bits>``
* ``<charconv>``
* ``<functional>``
* ``<type_traits>``
As an extension these types can be used in the following headers:
* ``<format>``
* ``<random>``
