----------------------------------------------------------------------

[~beobal] I've updated doc/SASI.md with LIKE support and fixed a typo in Cql.g, also I've noticed that loading of the SASI indexes on startup is missing so I've pushed that too into CASSANDRA-11067 branch (and fixed use of IntervalTree on the way) and rebased everything with the latest trunk.

Edit: I've also (just) added ByteBufferUtil.\{startsWith, endsWith\} to complement ByteBufferUtil.contains for LIKE_\{PREFIX, SUFFIX\} accordingly.

> I think everyone agrees that a LIKE operator would be ideal, but that's probably not in scope for an initial 3.4 release.
> Still, I'm uncomfortable with the initial approach of overloading = to mean "satisfies index expression."  The problem is that it will be very difficult to back out of this behavior once people are using it.
> I propose adding a new operator in the interim instead.  Call it MATCHES, maybe.  With the exact same behavior that SASI currently exposes, just with a separate operator rather than being rolled into =.
