Some updated timings below, all times are best-out-of-3 wall times, in
seconds. Patch #11900 is in progress so the timing is with the current
patch. "baseline" means sage-4.7.2.alpha3 without #9138. Clearly, the
slowdown of elltest2.sage is not due to #9138. Also Singular does not
cause a slowdown.
