Sounds good. Give it a few days, and delete if it still looks slow

That should use the same choices for div1 and div2. Is it important to
inline some or all of the div1/div2 code? If we move them out to
separate .c files, it gets easier to share between hgcd2 and
hgcd2_jacobi, and easier to experiment with assembly div1. But it gets a
bit more complex to set things up for tuneup.
