  Of course an array of n bit fields will always have the packing
pattern repeat after Least Common Multiple(n,8) bits, and thus
can be viewed as an array of LCM(n,8)/8 -byte records, each containing
LCM(n,8)/n fields.  If access to the J-th of a packed array of n-bit
items is most efficiently implemented on a particular machine by using
a case statement on the J/(LCM(n,8)/n)-th group, then by definition a
'smart' compiler for that machine does it that way.
