// A DenseSlabAlloc is a freelist-based allocator of fixed-size objects.
// DenseSlabAllocCache is a thread-local cache for DenseSlabAlloc.
// The only difference with traditional slab allocators is that DenseSlabAlloc
// allocates/free indices of objects and provide a functionality to map
// the index onto the real pointer. The index is u32, that is, 2 times smaller
// than uptr (hense the Dense prefix).
