The cl- prefix often carries overtones of "and something extra": e.g.
cl-mapcar is more general than mapcar, and so is cl-member more general
than just member.  cl-caddr is however identical to caddr.  But seeing
cl-caddr in source raises the subliminal question "what's it got that
caddr doesn't?"

Let's just put them all in subr.el, then.  All the cXXr definitions would
then be together.  The defaliases can stay in cl-lib.el.  I can't think
of anything that might go wrong.
