Updates project to LLVM 12 and GHC 9.
LLVM itself is on version 19. The llvm-hs bindings are not actively maintained. They have branches for 12 and 15. I investigated 15 but this has significant API changes and would require many changes to the project, so this is left for later.
We use a fork of llvm-hs-12 which updates bytestring so that there are no conflicts with GHC 9.2.8.
Add the LLVM installation requirement to the README with some notes on installing/building LLVM 12.
