Now that "key == Qunbound" is used to determine if a hash table entry is available, we can't stash pre-allocated vectors into the `key` slot anymore, so use the `value` slot instead. (make_log): Pre-fill the `value` slots i.s.o `key`. (evict_lower_half): Stash key back into `value`, i.s.o `key`. (record_backtrace): Get pre-allocated vector for `value` i.s.o `key`.
