Here's what I have staged for commit. I searched around for anything else
that might be missing, and I only found a couple of small things. First,
there are some optional AArch64 optimizations (simd.h and popcount) that
likely need more work, but those can wait for now. Also, while the patch
is targeting Windows 11 (IIUC), there are some notes in the docs that give
the impression Windows 10 is supported, too [0]. I could easily change it
to say that AArch64 requires Windows 11, but I don't know what to do with
the references to specific versions of Visual Studio and the Windows SDK.
Thoughts? Maybe that can wait, too.
