Now that the late stage of the decompilation pipeline is managed with revng-pipeline, and we have a standalone tool for decompilation, we have no need to use LLVM passes anymore for those stages. This commit also renames the directories to avoid the confusing Pass suffix, not what LLVM passes are gone.
