Instruction (vpgatherdd) that this implementation relied on turned out to be slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX implementation is therefore faster and this implementation should be removed. Converting this implementation to use the same method as in twofish/AVX for table look-ups would give additional ~3% speed up vs twofish/AVX, but would hardly be worth of the added code and binary size.
