BIGNUM
;;; Note: On the mips port space for a two word bignum is always
;;; allocated and the header size is set to either one or two words
;;; as appropriate. On the mips port this is faster, and smaller
;;; inline, but produces more garbage. The inline x86 version uses
;;; the same approach, but here we save garbage and allocate the
;;; smallest possible bignum.
