Description

At the moment, SASI indexed can work only with Murmu3Partitioner. CASSANDRA-12389 was created to enable support of one more partitioner with fixed-size tokens, although enabling variable-size tokens will need more work, namely skipping tokens, since we can't rely on fixed-size multiplication for calculating offsets in that case anymore.

This change won't require bytecode format changes, although supporting ByteOrderedPartitioner is not a very high priority, and performance will be worse because of "manual" skipping.
