Ok, thanks.

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.
