This can be useful to test improvements in LLVM master and to make it possible to support LLVM 11 for the most part already before the next release. That also allows catching LLVM bugs early to fix them upstream. Note that tests do not yet pass for this LLVM version, but the TinyGo compiler can be built with the binaries from apt.llvm.org (at the time of making this commit).
