Grr, not so easily, unfortunately. It was really a mistake that the
original one wasn't clang-formatted for some level of determinism like
this one is. As Mathias mentioned, --color-words -w makes it a lot
more clear what's going on. But actually, even with whitespace
unchanged, there's a *lot* of change in this patch because the
register allocation changed, so lots of %1 became %0 and suchlike.

It's probably easier to just look at
https://github.com/project-everest/hacl-star/commit/a9f1c5fa440b7e95e3d853671ee65b31ee5c473b
to see what's changed.

Alternatively, if you don't want to review this, that's fine -- just
say so -- and Herbert can go with Mathias' Reviewed-by, which might
make sense anyway because he spent a lot of time with this code.
