Florian Margaine 09899a3e15 Fix INCF on a THE variable. 
The following code:

(let ((foo 0))
  (incf (the fixnum foo) (bar)))

was being expanded into:

(let ((foo 0))
  (LET* ((#:G133 (BAR)) (#:G132 (THE FIXNUM (+ (THE FIXNUM FOO) (BAR)))))
    (DECLARE (:READ-ONLY #:G133))
    (SETQ FOO (THE FIXNUM #:G132))))

Which is obviously going to call (BAR) twice. If (BAR) has
side-effects, then it is going to be buggy.

The old define-modify-macro had an issue with out-of-order INCF/DECF,
which is why it was replaced with Bruno Haible's macro, which is
supposed to improve THE handling. It turns out that the improvement is
a bit broken, so we're just fixing this.

Fixes #401.
