intgemm_reintegrated_computestats

[kpu]

For use with the NMT students in 8-bit et al, the submodule should point at the intgemm_reintegrated_computestats branch of Marian. And it should set config options consistent with that. Maybe all that needs to happen is a change in submodule pointer.

I also want to assign @XapaJIaMnu but he's not in the repo yet.

I did a merge: https://github.com/XapaJIaMnu/marian-dev/tree/submodule_intgemm
@ugermann can you test if you can compile?

Thanks for the fork @XapaJIaMnu. Reassigning to @abhi-agg and @kdavis-mozilla who are responsible for integration and have regression tests running.
