Robert Suderman 26ac5baae4 Make mhlo.sort return variadic results instead of a tuple
Tuple is only used on XLA's sort to return multiple inputs. MLIR supports
multiple inputs, switch to a tuple return.

Mehdi Amini 7abd557a61 Add a header for table-gen generated pass for MHLO and use it in SinkConstantsToControlFlowPass
A non globally registered pass should define `getName()` in order to generate correct crash reproducers.
This is something we get "for free" when using the TableGen generated base class.
We should also migrate the other passes to the same mechanism and remove the static
global registration.
