Initial version of local-array-less gabor implementation
Initial version of local-array-less gabor implementation - added forgotten code
Initial version of local-array-less gabor implementation - cleanup
gabor - implemented shifting of calculation vector by one to enable higher compact ratio
gabor - changed cell grouping for vectored calculation, gained a little speedup
introduced a few SSE4.1 instructions
gabor - two approaches to the algorithm vectorization: 1) calculation mask with compacting   2) full vector utilization.   Approach 1) shows marginally better results
gabor - selected the compacting vectorization algorithm, plus some additional speed improvements
