//
// This probing function guarantees that after N probes, all the groups of the
// table will be probed exactly once.
//
// The control state and slot array are stored contiguously in a shared heap
// allocation. The layout of this allocation is: `capacity()` control bytes,
// one sentinel control byte, `Group::kWidth - 1` cloned control bytes,
// <possible padding>, `capacity()` slots. The sentinel control byte is used in
// iteration so we know when we reach the end of the table. The cloned control
// bytes at the end of the table are cloned from the beginning of the table so
// groups that begin near the end of the table can see a full group. In cases in
// which there are more than `capacity()` cloned control bytes, the extra bytes
// are `kEmpty`, and these ensure that we always see at least one empty slot and
// can stop an unsuccessful search.
