Similar to D92887, LoopRotation also needs duplicate the noalias scopes when rotating a `@llvm.experimental.noalias.scope.decl` across a block boundary. This is based on the version from the Full Restrict paches (D68511). The problem it fixes also showed up in Transforms/Coroutines/ex5.ll after D93040 (when enabling strict checking with -verify-noalias-scope-decl-dom).
