564482db30 Fix selection of IntSimdMatrix method 
Commit d36231e3e4 did not distinguish
between AVX and AVX2, so AVX2 code was enabled for IntSimdMatrix
even when only AVX was supported.

This resulted in an illegal instruction.

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.
