Normally return a compiled function if one argument, #'constantly.

* cl-extra.el (constantly):
Normally return a compiled function from #'constantly if we are
handed a single argument. Shouldn't actually matter, the overhead
for returning a single constant in a lambda form vs. in a compiled
function is minuscule, but using compiled functions as much as
possible is good style in XEmacs, our interpreter is not stellar
(nor indeed should it need to be).
