[PATCH] D67897: Fix __is_signed builtin

[Arthur O'Dwyer via Phabricator via cfe-commits]

Quuxplusone added a comment.

But `std::is_signed_v<float>` needs to yield `false`. Isn't it cleaner to leave the compiler builtin matching the library type-trait, so that the library doesn't have to check for integral types separately?
