\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Apparently using `refine eq_refl` rather than `subst <name for evar>; reflexivity` was resulting in βδ reduction of `chained_carries` in `carry_mulmod`. The β reduction resulted in us getting a different cps'd term. I do not know why this particular β reduction resulted in a 3x slowdown in partial reduction; it seems like anything that cared about sharing should either get sharing from the top-level in `carry_mulmod`, or should have no difference in sharing between the terms ```coq (fun n s c p idxs => fold_right (fun a b => @carry_reduce n s c a b) p (rev idxs)) n s c p idxs ``` and ```coq fold_right (fun a b => @carry_reduce n s c a b) p (rev idxs)) ``` This feels fragile, and I am mystified. Note for the future: I went about debugging this by integrating little bits of this PR one by one, seeing which one caused the slowdown, and then, when I realized it was use of `carry_mulmod`, I took the reified terms and made a goal asserting their equality, and then took the terms apart with `f_equal` and `extensionality` until I found the difference.
