...or 4, when 21 starts to be used...

> It is really unfortunate to require a 3rd llvm version to be built. On my "fast" arm64 machine llvm takes 4-5 hours, (amd64 seems to be 30-45 minutes?) so that is a significant time to replicate. Would it be helpful for me to test the ports that require llvm-19 and see if they still compile and work with llvm-20? Short of that I do not think it makes sense to build a third version of llvm for a single port. 

19 is a bit special because it's the same as the version in base, but
has the extra pieces which we don't/can't include in base. So I think
that probably warrants keeping.

Looking at the last bulk builds, times are roughly

amd64		2 hours
aarch64		3.5 hours
i386		5.5 hours
mips64		7.5 hours
sparc64		11 hours
powerpc		48 hours
armv7		112 hours

current status of the versions

16		used only for mozillas on aarch64
19		used for loads of things
20		unused/unlinked for now
21		unused/unlinked for now

how important is it to have zig 0.15? would it be too painful to stick
with 0.14 and llvm/19 until either there's a version using llvm/21 if
that gets linked to the build, or we can kill off llvm/16?
