treat push-down separately:
- List.length/len
- word.unsigned
and don't treat them as push-down, but as "compute len/unsigned of given expression
in a bottom-up way"
OR treat them as "local_simpl has access to an API to indicate how/where to continue
simplifying the new term"?
(would also work for (xs ++ ys)[i:] = xs[i:] ++ ys[i - len xs :],
where we have to indicate that (i - len xs) might need further simplification
set, app, repeatz, from, upto
Lemma len_set: forall (l: list A) i x, 0 <= i < len l -> len (set l i x) = len l.
Lemma len_app: forall (l1 l2: list A), len (l1 ++ l2) = len l1 + len l2.
Lemma len_repeatz: forall (x: A) (n: Z), 0 <= n -> len (repeatz x n) = n.
Lemma len_from: forall (l: list A) i, 0 <= i <= len l -> len (from i l) = len l - i.
Lemma len_upto: forall (l: list A) i, 0 <= i <= len l -> len (upto i l) = i.
pre-order vs post-order traversal:
len lemmas need to be applied before descending recursively, while others
need to be applied after descending recursively
some need intertwined application:
len_from should first simplify i (so that it's already simplified in the sidecond solving),
then simplify (len l) in a reusable way so that it appears simplified in the sidecondition
and in the rhs, and then apply len_from, and then simplify locally the rhs
(simplified_len_l - simplified_i)

(* Consider `word.unsigned (foo (a + 0) ^+ x ^- foo a ^+ y)`:
The argument of word.unsigned needs a first full bottom-up traversal to simplify
it into `x ^+ y`, and after that, another push-down-word.unsigned traversal to
obtain `word.unsigned x + word.unsigned y` (if no overflow).
On the other hand, if you start pushing down len too early, not a problem,
because list operations don't cancel like word.sub does.
Therefore, pushing down len could be integrated into bottom_up_simpl, whereas
pushing down word.unsigned runs *after* it in local_simpl_hook *)
