The Windows test failure shows that your change successfully simplified the IR generation for aggregate zero initializers.
Previously, it generated a sequence of `undef` and `insertvalue` ops, but now it produces a single `llvm.mlir.zero` op. This is a good improvement!

Since the generated IR has changed, the old `CHECK` lines for `undef` and `insertvalue` no longer match. Please update `mlir/test/Target/LLVMIR/Import/zeroinitializer.ll` to verify the new behavior:

```
; CHECK: %[[RES:.+]] = llvm.mlir.zero : !llvm.struct<"Domain", (ptr, ptr)>
; CHECK: llvm.return %[[RES]]
```
