bug#9668: 24.0.50; doc of `declare' (non-CL version)

[Drew Adams]

`(elisp) Defining Macros says' that `declare' works only for `debug' and
`indent'.  But the Emacs Lisp source code has lots of occurrences of
`doc-string', and `ignore' as well.  Seems like the doc is not
up-to-date?  (I'm not counting occurrences of CL's `declare special'.)
 
(And the `declare' doc string just refers to the manual - does not
describe the SPECS that it mentions at all.  That's probably OK.)
