[Mlir-commits] [mlir] [mlir][tensor] Add tests to invalid.mlir (PR #112759)

[Andrzej Warzyński]

https://github.com/banach-space created https://github.com/llvm/llvm-project/pull/112759

Adds two test with invalid usage of `tensor.extract_slice` that were
missing. Also moves one other test for `tensor.extract_slice`, so that
all tests for this Op are clustered together.
