Extend fusion root heuristic to also work in partially bufferized programs.
...
We now follow data flow though tensor_cast, tensor_load and tensor_to_memref
operations.

Consider aliases through control flow for lhlo-fuse-linalg.
...
This should handle scf.if and shape.assuming regions,
which we care about in kernel_gen.

Extend hlo-fuse-linalg slightly to support aliased returns.
...
The fusion heuristic identifies the root of a fusion by checking whether an
output of a linalg operation is a function result. It did not consider outputs
flowing through aliasing operations (like casts).

Move HLO tests to `third_party/tensorflow/compiler/mlir/hlo/`
...
Also add a localized `mlir-hlo-opt` binary for the testing of
tensorflow/compiler/mlir/hlo/... ; this directory is intended to be self-contained
and depend only on MLIR.
