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).

More cleanup in mlir-hlo to prepare for the standalone build
...
Shuffle files around, use TableGen to register passes, and introduce
a `mlir-hlo-opt.cpp` file to hold the main entry point of the -opt tool
and stop relying on static registration for dialect/passes.

Rename xla_lhlo dialect into lmhlo
...
Following on the plan of isolating the compiler/mlir/hlo directory.
Another xla_lhlo dialect will be created under compiler/mlir/xla/ later.

Move XLA-independent transforms to the new MLIR-HLO directory
...
This is as straighforward as possible, more cleanup/rewrite to come.
