I'll note that the CQL unit tests do that (being able to switch between
prepared vs unprepared with an environment variable) so what we should
do is migrate the dtests to unit tests (which has been discussed already).
I've created CASSANDRA-9160 to keep track of this (I though we had a ticket
that already but haven't been able to find it).

Similarly to what's above, it should be too hard to have the CQL unit tests
automatically use COMPACT tables when some environment variable switch is
providen. We could also implement some kind of randomization of parameters
that tests don't always run with the default settings. I've created
CASSANDRA-9159 to track that.
