HashSlotArray16byteKeyImpl(key1, key2) to a slot in the
array.
The returned object contains the slot value block address and whether a new
slot had to be assigned. The hash slot array implementation keeps a reference
to the returned object and will always return the same instance, albeit with
updated fields on each new invocation.
This means the returned object is valid until the next invocation of this
method.
Whenever this method returns a newly assigned slot, the caller must ensure that the null-sentinel value at the returned address is overwritten with a non-sentinel value.
