  Log Message:
  -----------
  [LoopPeel] Use llvm.experimental.noalias.scope.decl for duplicating noalias metadata as needed.

The reduction of a sanitizer build failure when enabling the dominance check (D95335) showed that loop peeling also needs to take care of scope duplication, just like loop unrolling (D92887).
