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.
