[mlir] Always create a list of alias scopes when emitting LLVM IR

Authored by ftynse on Sep 21 2021, 2:45 AM.



Previously, the translation to LLVM IR would emit IR that directly uses
a scope metadata node in case only one scope was in use in alias.scopes
or noalias metadata. It should always be a list of scopes. The verifier
change in 8700f2bd36bb9b7d7075ed4dac0aef92b9489237 enforced this and
broke the test. Fix the translation to always create a list of scopes
using a new metadata node, update and reenable the respective test.

Fixes PR51919.

Can you cross-check with ? I think you have the same fix but the test update is slightly different.
