[PATCH] D62825: [C++2a] Add __builtin_bit_cast, used to implement std::bit_cast

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

(You might argue that it's ridiculous to require that `nullptr_t` have the same size and alignment as `void*` but not have the same storage representation as a null `void*`. I'd agree, and I've raised this in committee before, but without success)
