Of course this change also affects Emacs running with nativecomp, as many calls to EQ are made by C functions not lowered by nativecomp. My guess is that nativecomp's performance would benefit quite a bit from the general approach of this patch, as every point where nativecomp calls C is a pessimization spot, but that's another topic.
