OK.
FWIW, I suspect that once we've all done tuning on our designs that we
will want to compare notes and hopefully come up with a good default
value over which we send to the libcall. Else we'll have to shove it
into the tuning structure. This flag ought to help us find that point
without having the rebuild the compiler for the various tests we're
going to need to run.
