;; This is needed because CCL assumes the pre-bigint (wrapping)
;; semantics of integer overflow.
;; The CCL compiled codewords are 28bits, but the CCL implementation
;; assumes that the codewords are sign-extended, so that data constants in
;; the upper part of the codeword are signed. This function truncates a
;; codeword to 28bits, and then sign extends the result to a fixnum.
