DEFUN and local declarations

[RMS at MIT-AI (Richard M. Stallman)]

DEFUN will now process ARGLIST and RETURN-LIST local declarations from
either an outside LOCAL-DECLARE or a DECLARE at the start of the body,
and put them into the debugging info of the NAMED-LAMBDA.

Also, any other local declarations from either source are put into a
DECLARE at the start of the body of the NAMED-LAMBDA, so that, for
example, any special declarations will be remembered if COMPILE is
used to compile the function later.
