Thank you for the excellent bug report. I wish the average report was half this

Running your example program with a profiler shows that the do_copy_propagation
and do_copy_propagation_elements passes are taking all the time.

I suspect this is because internally they use linked lists for the acp/kill
sets when they should be using hash tables. Ken fixed a similar problem in
commit 4654439fd.

I'll look into making this change.
