There are a few tests in `test/Integration/Dialect/Linalg` that have `-buffer-deallocation-pipeline`.

Yes, I'm in the process of fixing all memory leaks at the moment and this PR will bring down the number of leaking tests to 5 or so. The remaining ones are sparse compiler tests and they need a different fix (but they will eventually also use the buffer deallocation pipeline). To check for leaks, I built MLIR with `-DLLVM_USE_SANITIZER="Address"` and ran `check-mlir`. Ideally, we'd have a build bot that runs with ASAN.
