Remove logic to upgrade !llvm.loop by changing the MDString tag directly. This old logic would check (and change) arbitrary strings that had nothing to do with loop metadata. Instead, check !llvm.loop attachments directly, and change which strings get attached. Rather than updating the assembly-based upgrade, drop it entirely. It has been quite a while since we supported upgrading textual IR. llvm-svn: 264373
