Hi, I apply this patch in RVV downstrean. Tested it with a lot of vector
benchmark. It overal has a greate performance gain.
Maybe the last thing to merge this patch is wait for Richard Sandiford test it
in ARM SVE?
By the way, would you mind sharing the case list that GCC failed to vectorize

There's a new scalar cycle def kind, vect_first_order_recurrence
and it's handling of the backedge value vectori
Thank you so much. I will apply this patch and test it in downstream RVV GCC
