Thanks for adding :) One minor suggestion:
| // `count` if not found. | ||
| template <class D, typename T = TFromD<D>> | ||
| size_t FindLast(D d, T value, const T* HWY_RESTRICT in, size_t count) { | ||
| return FindLastIf(d, in, count, detail::FindEqualTo<T>{value}); |

It would be more typical to have a lambda here - let's remember to add HWY_ATTR before the opening { .
We can then remove FindEqualTo.
