Implementing P3666R4 Bit-precise integers, in libc++

P3666R4 Bit-precise integers was seen in LEWG in Brno last week, and importantly, LEWG approved that std::is_integral_v<_BitInt(N)> is true, and approved the general design direction in §5 of the paper. _BitInt(N) support in libc++: investigations, possible improvements: looking for guidance points out that we already support _BitInt in the standard library in various places, which is actually a bit of a problem. The proposal ensures that _BitInt is supported basically nowhere (other than type …
