This PR proposes to remove support for LLVM 8 in the next release. One motivation is that LLVM 8 is not supported on our CI, so this change would ensure that we're only shipping things tested in our CI. Also note that this only removes support for linking against the LLVM 8 library; users can still read bitcode generated with LLVM 8, as newer LLVM versions are back-compatible with bitcode from older versions.
