Inconsistency between AVX2 and SSE42 in ECM-14.0

Encoding and decoding go well with both SIMD options in RA, but results between AVX2 and SSE42 are different: bitstreams, BDrates and PSNR are all different from the 3rd encoded frames. It seems bit-exact for the I frames. Of course, if encoder and decoder do not use the same SIMD option then there are some decoding mismatches and/or crash. And it is impossible to know which SIMD option gives the good result since SCALAR option is broken.
