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.

Tres Popp 4251630426 Support CHLO broadcasting operations between scalar and unranked tensors. 
This is done through reshaping the unranked tensor into a 1D ranked tensor which will result in a safe broadcast/indexing logic when the other operand is a scalar.

Mehdi Amini 8900222fed Rename `xla_hlo` dialect to `mhlo` 
This is part of the current refactoring of the HLO related dialect.
`xla_hlo` will be reintroduced in a new form 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.
