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.

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 36ddbeb6b2 Remove the dependency on global dialect registry from mlir-hlo

Mehdi Amini cd01bb4c4e 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.

Mehdi Amini 7c4a5d62b5 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.

Mehdi Amini 31dc1b21eb Move XLA-independent transforms to the new MLIR-HLO directory
This is as straighforward as possible, more cleanup/rewrite to come.
