Thanks; this was indeed a lot easier to review. Mostly
this is OK, there are a few things:
 * minor style issues
 * handling of very large shift counts is not right
(both in code you wrote and existing routines)
 * the shift-and-narrow loop doesn't handle the case
where pass 1 reads registers pass 0 writes

I have patches which (sitting on top of your 6) fix all
these and give a clean pass on the random instruction
set testing for the shift instructions.

Unless you object, I think the simplest thing will be for
me to just fix the minor nits I identified in your patches
and then post a combined series of your patches and
mine.
