Patch at
http://gcc.gnu.org/ml/gcc-patches/2005-02/msg01571.html
improves the testcase from 16.2s to 12.1s (3.4: 5.0s) - aka, still not good
enough. As we have (with the patch) still size estimates for the functions
that are 15-40% higher than for 3.4 we'd probably need to bump our inlining
limits accordingly, say by 20%.
