:mrdocs:

Return an unspecified value such that, for any object `x` where `owner_equal(x)` is true, `owner_hash() == x.owner_hash()` is true. Note that this is based on the hash of the address of the `BloombergLP::bslma::SharedPtrRep` object used by this object. Note also that for two empty smart pointers `x` and `y`, `x.owner_hash() == y.owner_hash()` is true.
