[newlib 14/22] cpuset(9): Add CPU_FOREACH_IS(SET|CLR) and modify consumers to use it

[Sebastian Huber]

From: Mark Johnston <markj at FreeBSD.org>

This implementation is faster and doesn't modify the cpuset, so it lets
us avoid some unnecessary copying as well.  No functional change
intended.

This is a re-application of commit
9068f6ea697b1b28ad1326a4c7a9ba86f08b985e.
