Backports from C++17.

A listing of some of the features backported:

• From the language proper: std::byte (see also to_byte() ) .
• From <algorithm>: clamp() .
• From <cstddef>: to_integral() .
• From <functional> : not_fn() , invoke() (down to C++11 only).
• From <iterator>: container data globals data() , size() , empty() .
• From <numeric> : gcd() , lcm() .
• From <tuple>: make_from_tuple() , apply() .
• From <type_traits>: make_void , void_t , bool_constant , etc.
• From <utility>: as_const(), in_place_type , in_place_index etc.
