These instruction included a partial update of the output register in their SSE versions.
AVX, and AVX512 versions of the same instructions canceled the partial register update by passing an additional operand, that it's value will be copied to the rest of the output register.
No partial register update => The folding should be performed normally (not only when optimizing for size).
