Rename cl-func to cl-functions.  Enable it by default.
Turn off cl-functions warnings if the file loads cl.
(byte-compile-initial-macro-environment): For eval-and-compile,
use byte-compile-eval-before-compile to eval.
(byte-compile-eval-before-compile): New function to turn off
cl-functions when appropriate, for eval-and-compile.

(byte-compile-warnings):  Add cl-func option.
(byte-compile-cl-warn): New function.
(byte-compile-form): Use it, to warn about calling cl functions.
