Stephan Herhut 0c7152e65c 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.

Tres Popp be9ae88eaa 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.

Alexander Belyaev 3d930d08c2 [HLO] Delete LHLO memref cast ops and migrate to STD ones.

Stephan Herhut 2e30b59ddc 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).

Mehdi Amini fa057cc0bc 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.
