How would that work for LLVM?
libc++ / libcxx are rather small projects so Appveyor works well for them.
But LLVM as a whole is *huge*.
It takes ~50 minutes (1 hour let's say) to build it for me with 8 cores.
Appveyor builds are 2-4 cores, and severely ram-limited.
So it would take 4..2 hours at best to build, and then there's tests.
It doesn't sound all that promising?

(also, only a single build at a time)
