`template<class T> constexpr T byteswap(T x) noexcept;`
* *Requires:* `T` must be an integer type (i.e. one of `char`, `signed char`,
`unsigned char`, `short`, `unsigned short`, `int`, `unsigned int`, `long`,
`unsigned long`, `long long`, `unsigned long long`) without padding bits.
* *Returns:* `x` with the storage bytes reversed.

[section Changes in 1.83.0]
* Add support for incomplete types to [link core.type_name `boost::core::type_name`].
* Added support for incomplete types to [link core.type_name `boost::core::type_name`].
* Bit manipulation functions in [link core.bit `boost/core/bit.hpp`] are now
`constexpr` on recent MSVC versions (VS2019 update 5 and later.)
* Added `boost::core::byteswap` (an implementation of `std::byteswap` from
C++23) to [link core.bit `boost/core/bit.hpp`].
