502bb624c2 More optimisations for IntSimdMatrix 
* Move IntDotProductSSE. That allows inlining of the code.
* Improve IntDotProductSSE by moving some instructions.
* Remove unused num_input_groups_ from IntSimdMatrix.
* Re-order elements in IntSimdMatrix to avoid padding.

This fixes a regression which was introduced by commit
5c6a57b727 which removed
the definition for USE_DEVICE_SELECTION.
