The only problem that I see with this is that a compiler that understands
Neon intrinsics but not SVE ones will probably fail because we build
external functions that call the Neon versions in that case. But that's
easy enough to work around by adding an extra #elif defined(USE_NEON)
section, and it still saves a handful of lines of code. Perhaps someday
this situation will be rare enough that we can remove that hack and just
point to the portable versions if the compiler doesn't understand both Neon
and SVE, but I'm not sure we're there yet.
