5e831c548f Revert "Add 1D version of vpx_sum_squares_i16" 
This reverts commit f19700fe52850d051e505ec1b085f25060f7d054.

This crashes in SSE2/SumSquares2DTest.RandomValues/0 under x86 due to
alignment issues

abd00505d1 Add optimized vpx_sum_squares_2d_i16 for vp10. 
Using this we can eliminate large numbers of calls to predict intra,
and is also faster than most of the variance functions it replaces.
This is an equivalence transform so coding performance is unaffected.

Encoder speedup is approx 7% when var_tx, super_tx and ext_tx are all
enabled.
