Giuseppe Ottaviano 8f927e5f75 Fix undefined behavior in Hash 
Summary:
Instead of ignoring UBSan checks, fix the negative shifts in
Hash(). Also add test to make sure the hash values are stable over
time. The values were computed before this change, so the test also
verifies the correctness of the change.
Closes https://github.com/facebook/rocksdb/pull/2546
