Previously, this logic lived in the LLVM backend's matching compiler. When we eliminated the backwards dependency edge between the backend and the frontend, this meant we couldn't use the frontend pretty-printing logic to make the error message in the pattern matcher. This commit reinstates equivalent pretty-printing logic in the frontend.
