Won't be fixed on the 4.0 and 4.1 branches.

Numbers for  -static -O3 -march=pentium4 -fomit-frame-pointer  (on a P4)

3.4.6:  8.1s
4.0.3:  7.3s
4.1.1: 13.5s
4.2.0:  4.2s

(is there a correctness check inside the benchmark?)

with FDO:

3.4.6:  5.8s
4.0.3:  9.8s
4.1.1: 10.5s
4.2.0:  4.2s

indeed interesting that we loose on FDO for 4.0, and bad
that we're that much slower for 4.1.  Good for mainline though.
