Benjamin Kramer f4414fcd66 [MHLO:Linalg] Add support for lowering unsigned ops 
This strips away the signedness with a type converter, using unrealized
conversion casts. The rest is mostly mechanically pushing the original op down
the pipeline so lowerings can see the original types.

Signed types stay signless for now. This can be changed in the HLO bridge later.

I did a pass over all ops and added unsigned lowerings where they were missing.
There may be more.

Currently the lowering will die at a later stage because it doesn't understand
the unrealized casts.
