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.

Stephan Herhut c44e08351d Fix mhlo to lmhlo conversion for ReduceOp. 
The existing conversion no longer worked and was not save to undo. Furthermore, the pattern for mhlo.return had been removed.

Also adds some tests to ensure this does not degrade again.
