This seems rather like a hack for our not-so-capable loop unroller. The
estimator already correctly knows that much of it will be optimized away,
hence it would make more sense for the code emitter to also not emit
us

Adding a simple limit on number of loop nests in recursive inlining is easy
thing to do, but I am not quite sure how useful it is (well, overall recursive
inlining tends to help only few very special benchmrks).
