    sb-alien: some alien refactoring

      * Rename EXTRACT-ALIEN-VALUE & DEPOSIT-ALIEN-VALUE to %ALIEN-VALUE and
        (SETF %ALIEN-VALUE).

      * Split HEAP-ALIEN-INFO-SAP-FORM field into HEAP-ALIEN-INFO-ALIEN-NAME and
        -DATAP. HEAP-ALIEN-INFO-SAP-FORM becomes a function that conses up the form
        for the compiler, and HEAP-ALIEN-INFO-SAP replaces EVAL of the form.

      * Better error checking in PICK-LISP-AND-ALIEN-NAMES, and an error message
        that explains the correct form.
