Simplify and optimize `VecCache`'s `SlotIndex::from_index` Simplify and optimize `SlotIndex::from_index` Break out bucket 0 (containing `idx < 4096`) as an early return, which simplifies the remainder of the function, and allows optimizing the `checked_ilog2` since it can no longer return `None`. This reduces the runtime of `vec_cache::tests::slot_index_exhaustive` (which calls `SlotIndex::from_index` for every `u32`, twice) from ~15.5s to ~13.3s. Separately, simplify the test case as well. (The old and new code passes with the old and new test case.) --- Noticed because `slot_index_exhaustive` stood out as taking unusually long compared to other tests, so I started investigating what it was doing.
