C TODO
C  * Consider using special code for small n, using something like
C    "switch (8 * (n >= 8) + (n mod 8))" to enter it and feed-in code.
C  * The non-nc code was trimmed cycle for cycle to its current state.  It is
C    probably hard to save more that an odd cycle there.  The nc code is much
C    cruder (since tune/speed doesn't have any applicable direct measurements).
C  * Without the nc entry points, this becomes around 1800 bytes of object
C    code; the nc code adds over 1000 bytes.  We should perhaps sacrifice a
C    few cycles for the non-nc code and let it fall into the nc code.
