minor threepass optimizations and thier2 variant that uses threepass (but does unnecessary work in that case: allocation, extra copies, extra step for partitioning, etc)

added three-plus-one pass radix which performs very well, but there is 0.8 ILP only because of lot of cache misses. worse perf on random than magyarsort, but better than ska_copy and best worst cases - might hook into thier2?
