  -----------
  [libc++] Remove one of the std::signbit overloads (#130505)

We'e specialized `std::signbit` for signed and unsigned integral types
seperately, even though the optimizer can trivially figure out that
`unsigned_value < 0` always false is. This patch removes the
specialization, since there is really not much of a benefit to it.
