bug#25627: 25.1; `help-make-xrefs' loads `cl-extra.el' now

[Drew Adams <drew.adams@oracle.com>]

`help-make-xrefs' in `help-mode.el' calls `cl-some', which is defined in
`cl-extra.el' as an autoload.  Should we really be loading `cl-extra.el'
now, as soon as a user does, for example, `C-h f'?  In that case, what
is really "extra" about it (for interactive use of Emacs, at least)?

I thought that the point of creating `cl-lib.el' was to give people a
library of the most-used CL constructs and still let them avoid loading
all of `cl.el'.  If we are, in effect, loading `cl-extra.el' now nearly
by default then what's the point of separating out `cl-lib.el'?

Is this use of `cl-some' perhaps just due to laziness?  It's not hard to
get the same effect without using it and loading `cl-extra.el'.
