   these tables are used by several macros in the cfb code.

   the vax numbers everything left to right, so bit indices on the
screen match bit indices in longwords.  the pc-rt and Sun number
bits on the screen the way they would be written on paper,
(i.e. msb to the left), and so a bit index n on the screen is
bit index 32-n in a longword
