convolve8 sse2 test

convolve8 sse2 test

This experiment shows that when frame size is 64x64
vpx_highbd_convolve8_sse2 and vpx_convolve8_sse2's speed are similar.
However when frame size becomes 1024x1024
vpx_highbd_convolve8_sse2 is around 50% slower than vpx_convolve8_sse2
we think the bottleneck is from memory IO
