This patch isn't right. The underlying problem that loop
unswitching was having was that it wasn't considering an
infinite-loop CFG pattern to be a "side effect". It was
assuming that the loop would exit eventually, and that
by eliminating the infinite loop, it thought it was just
accelerating that :-).
I went ahead and fixed this on trunk.
