+# Optimization including two of Pavel Semjanov's ideas, alternative
+# Maj and full unroll, resulted in ~20-25% improvement on most CPUs,
+# ~7% on Pentium, ~40% on Atom. As fully unrolled loop body is almost
+# 15x larger, 8KB vs. 560B, it's fired only for longer inputs. But not
+# on P4, where it kills performance, nor Sandy Bridge, where folded
+# loop is approximately as fast...
