```coq
Lemma last_filter_postfix P `{!∀ x : A, Decision (P x)} l x
last (filter P l) = Some x →
∃ l1 l2, l = l1 ++ [x] ++ l2 ∧ Forall (λ z, ¬ (P z)) l2.
```
(and its counterpart for `head`)
The lemmas seem useful and general enough to fit in stdpp.
The `last` lemma derives the property `Forall (λ z, ¬ (P z)) l2` of the postfix of a split `l1 ++ [x] ++ l2` for a list `l` whenever `last (filter P l) = Some x`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/363Add lemmas `app_cons_eq_inv_{l,r}`.2022-01-14T15:31:17ZRobbert KrebbersAdd lemmas `app_cons_eq_inv_{l,r}`.This MR contains two commits: One with the actual lemmas, and one to perform some rearrangements.

The lemmas in this MR generalize the ones in !356. They also allow proving a variant for `suffix_of`, which is missing in that MR.
