Verify that !noalias, !alias.scope and llvm.experimental.noalias.scope arguments have the format specified in https://llvm.org/docs/LangRef.html#noalias-and-alias-scope-metadata. I've fixed up a lot of broken metadata used by tests in advance. Especially using a scope instead of the expected scope list is a commonly made mistake.
