bug#16520: 24.3.50; cl-defstruct with :predicate option

From: Helmut Eller
Subject: bug#16520: 24.3.50; cl-defstruct with :predicate option
Date: Wed, 22 Jan 2014 11:06:34 +0100

Compiling this code:

  (require 'cl-lib)
  (cl-defstruct (foo (:predicate foop)))
  (defun bar (x) (cl-check-type x foo))

with with:  emacs -Q -batch -f batch-byte-compile foo.el
produces this warning:

  foo.el:8:1:Warning: the function `foo-p' is not known to be defined.

and since foo-p is not defined will also lead errors at run-time when
bar is called.

Adding eval-and-compile to the structure definition avoids the problem
but it's a bug that the compiler emits a call to foo-p at all.
