The thing to keep in mind is that the .S was not directly and blindly
generated from the .pl. We started with the output of the .pl, and
then, particularly in the case of x86_64, worked with it a lot, and
now it's something a bit different. We've definitely spent a lot of
time reading that assembly.

I'll see if I can improve the readability with some register name
remapping on ARM. No guarantees, but I'll play a bit and see if I can
make it a bit better.
