That was more or less the idea.  But I kind of figured someone would just
tell me which one to do without actually doing any timings.  This patch
(applies after the cpuclocks patch) makes the one decision, to use
conditional branches rather than indirect calls in the common case.
That is consistent with what the old code did.
