It's too bad that we don't have that test mergeable at this point, but I 
guess we can't hold back the new aarch64 assembly due to that...

The patches seem fine as noted before; I found some more cases of missing 
trailing newlines at the end of the file, and some other minor stray 
changes in the patches, which I fixed. I also amended the commit messages 
saying that some of the benchmarks are from the non-merged checkasm test.

With that, I pushed these patches.
