<<I suggest we drop it to 100 or 1000 instructions by default, and see
how that does. We could *still* use better heuristics, but that might
make things better in the typical case -- enough so that we might
not need the better heuristics just yet. And, now that all this
stuff is run-time tunable, users can always crank the number back
up if they need to.

I would think that 100 is just fine, and I cannot imagine any user needing
to deoptimize their program by cranking the number up (it is equally hard
to imagine any program that would be measurably improved by the old limit,
but very easy to imagine programs that are damaged).
