vf_psnr: sse2 optimizations for sum-squared-error.
The internal line accumulator for 16bit can overflow, so I changed that from int to uint64_t in the C code. The matching assembly looks a little weird but output looks correct. (avx2 should be trivial to add later.) Reviewed-by: Paul B Mahol <onemda@gmail.com> Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
