[Mlir-commits] [mlir] [MLIR] Incorrect track of usedKey in setPropertiesFromParsedAttr (PR #144789)

[Chao Chen]

https://github.com/chencha3 created https://github.com/llvm/llvm-project/pull/144789

Currently, the generated `setPropertiesFromParsedAttr` uses `usrdKey` to track "true" or "false" instead of attribute name, e.g., `usedKeys.insert(StringAttr::get(ctx, "true"));`. I am not sure whether it is a typo or designed to retire the use of attribute for property. Can someone help to check?

I will create a test if it is confirmed a typo. Otherwise, I will drop the PR.
