brilliant. btw do check email from David.

there is quite a lot of "small" work needed on SVP64 as well,
we cannot move to libopid because it is too massive a change
(and needs its own entire grant)

remember that we don't yet have these in the simulator and
therefore not in insndb, but the csv entries and OP_xx should
be reasonably straightforward to add.

* cntlzdm/tz should have the same OP_CNTLZ as existing instructions
* set?bc* should have the same OP_SETBC
