Work on this how.  This one bit is probably the biggest problem in
your code.  While the rest also needs a considerable amount of work,
this part is the one that you still have not clarified very well.

What are you trying to achieve here, and what kind of insns are you
trying to combine?  If you described the problem instead of a bad
solution, maybe people can help you figure out a good solution.
