State-Changed-Why:
While this section of <sys/types.h> is going to be moved to
<sys/select.h> the issue pertaining FD_ZERO won't change.
Changing the documentation would be fixing the wrong issue
since POSIX expects this to work with <sys/select.h> alone
(changed in post-2-0); pulling in <string.h> or privately
declaring memset() isn't an option due to namespace constraints.

Some options:
* inline this; on amd64 the observed performance impact is a
  factor of ~1.57x;
* use the gcc builtin if applicable, fall back to inlining
  (I have some qualms about using gcc builtins at that level);
* push this down to the MD level and optimize; at the same
  time a change to a __fd_mask type suiting the machine better
  might be considered
