There are other benchmarks. Some of them are on gcc.gnu.org
somewhere (there's a link off the web pages). Try them and
see if we regress -funroll-loops.
Note that I have no confidence that -funroll-all-loops is a
useful thing to try. You're overriding the logic in the
unroller that tries to decide if the unrolling would pay off.
