[LoopUnroll] Use llvm.experimental.noalias.scope.decl for duplicating noalias metadata as needed
This is a fix for https://bugs.llvm.org/show_bug.cgi?id=39282. Compared to D90104, this version is based on part of the full restrict patched (D68484) and uses the `@llvm.experimental.noalias.scope.decl` intrinsic to track the location where !noalias and !alias.scope scopes have been introduced. This allows us to only duplicate the scopes that are really needed.
Notes:
- it also includes changes and tests from D90104
