Contrary to the author's claim, ART is not really based on the LLVM toolchain. It has an LLVM based backend implemented, but it is not the production one and is not used on any device. I don't remember offhand if they have future plans for it, but at the time, it turned out to not be the best engineering option, and hasn't been touched in a while. The main compilers used are the quick one and the optimizing one. You can see this yourself, since ART uses AOSP as it's master.
