No, it regressed again.

With -O2/-O3 -funroll loops -fswitch-loops -fpeel-loops, mgrid (and swim) no
longer regress. With just -O2/-O3, performance regression for mgrid remains
(and swim performance dropped dramatically).

I looked at the code generation after Zdenek's patch for PR 19701 and it looks
much better but I don't
have a machine to test SPEC on.

PR 19701 is an example of where ivopts causes a regression in that we create
too many IVs.
